Sg3525 Ir2110 Smps Rar Files
Hi i'm going to start my first audio smps.i want use it for my Nmos200: +/-40v 5A 2X200W@2Ohm - 600W max power consumption = +/-40v 7.5A per rail i was read this thread: ) now i'm confused i don't know which circuit is suitable for me! IR2153 or IR2110+SG3525 it's because at first, ludo built the ir2153 based circuit but in newer version, he was build 3525+2110 based circuit and result was more reliable. Can anyone help me about this issues?

There is the latest version of Ludo's IR2110+SG3525 based circuit, please tell me about it, it's OK? Thanks MicrosiM But i think that schematic have a lot of problems: - the output voltage not adjustable, what you think?
- the Snubber circuit behind the mosfets (5R6+330pf), it's a copy from QSC PLX1802 Schematic! It's ok for this circuit? That circuit use IGBT and worked in resonant mode.
what about current sense inductor? Please tell me about winding and core specs. main transformer was calculated based on excel file and you can download 80V design on the attachment. I got minimum voltage of the 220v line around 200v, then 200v X 1.41= 282v/2 = 140v, you can see another parameters on excel file.
on current limit circuit, how much is the P1? - the output inductor maybe in wrong place, it's must be after the rectifier, also i don't know the good specs for that. I'm sorry for asking too meny questions.

on current limit circuit, how much is the P1? P1 value, start with 50K - the output inductor maybe in wrong place, it's must be after the rectifier, also i don't know the good specs for that. No need for those output inductors, since its not a REGULATED SMPS I'm sorry for asking too meny questions -. Calculations for transformer is OK Dont forget Making this SMPS from scratch, like in your case, will need things to be done right I advice you to ask about every thing.

Don't worry it's not my first 220v smps, i have made 100w 18v smps about 1 years ago, but design based on pi-expert. I'm also download very useful pdf files from this forum to learning about construction, winding, calculation and many other things, thank you for supporting 'DIYSMPS' what's your opinion about 16v 0.5A auxiliary smps? I want to design and replace it for pcb transformer.
Anyway, i think designing this PCB will be difficult i'm also going to buy Rigol 100mhz Scope and X100 Probe, also isolation transformer - the schematic at version 0.1 also available, but i'm not grantee the operation of this circuit before testing it.
Hi all, I am working on making a switched mode arc welding machine with maximum 150A current and 30-40V. I have done most of the circuitry but the problem I face is the output current control.
I do not want to use the bulky old linear type inductor, so what can be the solution? I have seen in some SMPS welding machine (in schematics), current is controlled with a small ferrite core inductor. I tried to find out the calculation and procedure, but could not find out from any book or internet the required procedure for controlling output current through ferrite core inductor.
I require to control the output current to control the inrush current and also to use different type of welding rod with controlled current from 75A to 150A. In some discussion on some forums, I found the idea of controlling output current through hall effect sensor.
But nowhere it is discussed in detail. So, no concrete idea could have been formulated. Help in this regard will be appreciated. Linear Current control in SMPS is difficult, you can use a hall effect sensor from LEM.
In lower current application upto 50 Amp i had used a Current sense resistor and an OP amp OP37 as the amplifier stage, with a low offset op amp the shunt dissipation can be kept low with the sense voltage in the range of 10 millivolt, this will be a lower cost approach than a Hall based design. Hi, This is current sensing, but I require to control the current flow with my requirement to use different sizes of welding rod and current control should be from 50A-150A.
I think with your proposed system sensing can be done but current control can not be done. However I appreciate your reply and please let me know if any other ideas are there for switching type control. I tried with Pic Micro controller and Triac by Line Phase Angle control but in that case Voltage also reduces, which is not acceptable as Voltage should be constant for good Arc Welding.
For Sohel, I appreciate your reply but the Link you have provided will not serve my purpose and I have consulted that earlier. « Last Edit: January 05, 2009, 05:54:49 17:54 by tAhm1D » Logged. Hi From your state '. Have done most of the circuitry' and previous post, I suppose you design the SMPS. I saw some IC (linear technology) that use a double feedback for regulation, one from voltage or-ed with one from current. Why not use a similar approach? Use two signals and or then to the feedback.
The voltage one will limit the maximum output the current will work during welding. More or less like a power supply when limits the output current. The setting/adjust may be made on the reference or better on the feedback signal. You did not specify if your design output is AC, DC or both. « Last Edit: January 05, 2009, 11:32:12 23:32 by DTiziano » Logged.
Hi DTziano, I appreciate your Idea. But it is not fully clear to me. If you elaborate in detail, it will be useful for me to grasp. My design output is DC and it is SMPS type. I did not find yet the Linear Technology reference. Anyway, any power supply has set point and feedback, or should be. Suppose a configuration with “voltage” set point.
Add a current measurement circuit and a comparator with a threshold set point (current set point) that when the current exceed (current set point) will reduce the voltage set point. That is the basic idea. A linear simple conceptual implementation can be made by OP AMP (as a comparator) driving an open collector transistor that shunt the voltage set point. On SMPS the power stage (pulse generation) cut off for one or more cycles may be easy to do and simple to balance (loop stability). Hi tAhm1D, I can't understand what is the exactly electrical schematics of your SMPS welding machine. What type is your switching power supply circuits: Push-Pull (with two power MOSFETs and one center-tapped transformer), Half bridge (with two transistors, two center tapped capacitors and one transformer) or Full bridge (with four transistors and one transformer). Depending on circuits you can use a ready PWM IC's (TL494, SG3524 or SG3525) or some digital switchmode regulator made it with some MCU's (PIC or AVR).
For output current feedback you can use one of the known solutions: current sense resistor, current transformer or Hall-effect sensor. Choice is your. And you must maintain a constant output current not a voltage. And this can be made with PWM control of the output voltage (by the switchmode power supply circuit). There is a one paper related with current measurement and current sensors in SMPS: Best regards.

I am also not an expert in welding. But I am interested in the project as it will help ultimately in numerous fields in Electronics in controlling current. Let me clarify you all regarding the Modalities of my Project. It is smps type. First, I will rectify the Line Voltage to DC and then convert it in required voltage by Full Bridge Topology and before again converting it to DC, I will channel this 100khz Ac through saturable core transformer/inductor to ensure required amount of current and then it will be converted to Dc and will be supplied. For proper Arching, min voltage is required, it should be 40-45v for using any size of welding Rod,but with the reduction of the size of welding rod for welding less sized material, less amount of current is required. That is why, I want to keep the voltage constant to around 40v and current should be changed from 50-150A according to requirement.
Yes, saturable reactor is variable impedence device, a Ferrite Torroid Core which will have the winding of the main wire and at the same time different wiring will be there with Dc controlled supply,which will saturate the core according to requirement to control the flow of current. Hope, I could make you understand my modality.
I am at the final stage of preparation, and it will take some time to finalize. Your all positive suggestions will be accepted with gratitude. « Last Edit: January 09, 2009, 10:10:52 22:10 by tAhm1D » Logged. I think I can be of assistance.
I assume that you wish to build a welding power source suitable for MMA (stick electrode) welding. If this is correct the power source will have to provide a roughly constant current output characteristic (I will expand on this later). For ease of arc striking a no load voltage voltage of 50 volts would be preferable, the arc running voltage will be dependent on a number of factors (I will also expand on this). My main concern is with the operating frequency of 100Khz. Unless you intend to make a complex resonant ZVS or ZVC system you will have to limit the frequency to 20-30Khz for an IGBT design. Any higher than this then you will have to use power MOSFET's.
I will post some more information over the weekend Logged. Hi All, I am almost at the final stage of my Project. Here, I have used the Saturable Core Reactor,to control the Output Current Flow. The principle of which I tried to show with the following schematic. Controlling the AC current across the lamp L with the DC current, regulated by variable resistor R. B- battery, G - AC source.
Still I am facing some problems to finally control the output current. Further suggestions are invited to overcome the problem.
« Last Edit: January 11, 2009, 07:05:50 19:05 by tAhm1D » Logged. Sorry for the delay in replying until now tAhm1D. With an output current of 150 amps you will easily be able to weld with 3.2mm electrodes and you will just have enough current to weld with 4.0mm electrodes. The power source will have to provide enough voltage to maintain an arc at the maximum output current. According to specification EN60 974-1 the required voltage at 150 amps will be 26 volts.
This is given by: - V=0.04 X Imax +20 (for MMA only) It is possible to to weld with lower output voltages but it becomes more difficult to maintain the welding arc. Maximum output power will = 3900 watts. With an overall conversion efficiency of 80-85% the primary inverter will have to be able to provide about 4500 watts of power (a lot!).
Have you thought of using a half bridge design? I have been involved in 3 phase half bridge designs producing more than 25 kilowatts out. A half bridge design will certainly be easier to implement (at least that's my experience).
One more question, I assume the input voltage will be 230 volts single phase? Hi okk, I have studied your reply and found it useful. I am thinking about 230v or 380v Ac input or both. I have planned to use Full Bridge Topology but after your suggestion, will think regarding half bridge also.
I have decided to put no load voltage= 45v and with load according to requirement. If you kindly provide me voltage and current requirement for Arc Welding (MMA) according to specification EN60 974-1 or source,from where I can collect the data, it will be of great help for me. I am just calculating basing on datas provided by an Expert welder. Hope for your further help. Hi Okk, I have considered using half-bridge topology, but there are some disadvantages to using half-bridge.
Opposed to full-bridge where peak current is 1.4 times nominal current, in half-bridge topology peak current is 2.4 times nominal current. So here the MOSFETs will have to handle greater current. But the main disadvantage I find is that, half-bridge topology relies greatly on the input bulk capacitors as opposed to full-bridge where the circuit relies on all the MOSFETs. Thus I find it is riskier to use Big Capacitors at such high powers and MOSFETs are safer and cheaper as well. So my decision stands at using full-bridge topology.
I will be looking forward to your suggestion. Hi, Though I am highly inclined to Saturable Core Reactor method to use in Current controlling, I am also getting some knowledge regarding the latest mode, that is Hall Effect Sensors. From bbarney's Link in this Post regarding Allegro Microsystem and the beautiful Book on Hall Effect Sensor posted by good friend ravenfeather in the link:helped me to formulate a concrete Idea regarding current control through Hall Effect Sensor.

I am working on it and hope to get more ideas/suggestions in this regard, so that I can utilize those in my Arc welding Project. Hi tAhm1D, I am also working on inverter power supply for tig/mma welding. Currently I have built the prototype smps of 1500W. Today, I am going to test it and verify all design parameters.
I have not yet implemented the linear current control for simplicity. But, sooner or later I am going to work on it. For prototype I am using fix output current control using current sense transformer. The circuit is comprising of UC3879 main control, Ir2110 driver and center tap output configuration. On this center tap winding, I have placed the current transformer. In future, I am planning to change the CT's fix gain to variable gain using Opamp, to achieve variable current control. Yet I have not implemented it, but I thought it is the best method to control output current.

The social and cultural life revolves around the (the oldest in Romania), the, the, the, a famous (the oldest and largest in Romania), the (the oldest in Romania), the high quality cultural centres and festivals, an array of museums, memorial houses, religious and historical monuments. The city is also known as the site of the largest Romanian pilgrimage which takes place each year, in October. In 1640, established the first school in which the Romanian language replaced Greek, and set up a printing press in the ( Monastery of the; built 1635–39). Between 15 September - 27 October 1642, the city hosted the (also referred to as the Council of Jassy). In 1643, the first volume ever printed in was published in Iași.
The city was burned down by the in 1513, by the in 1538, and by troops in 1686. In 1734, it was hit by the. It was through the that the sixth was brought to a close in 1792. A Greek revolutionary manoeuvre and occupation under (Αλέξανδρος Υψηλάντης) and the (Φιλική Εταιρία) (1821, at the beginning of the ) led to the storming of the city by the Turks in 1822. In 1844 a severe fire affected much of the city.
Mid–19th century to 20th century. Union Square Between 1564 and 1859, the city was the capital of Moldavia; then, between 1859 and 1862, both Iași and were de facto capitals of the of Moldavia and Wallachia.
In 1862, when the union of the two principalities was recognised under the name of Romania, the national capital was established in Bucharest. For the loss caused to the city in 1861 by the removal of the seat of government to Bucharest the voted 148,150 to be paid in ten annual instalments, but no payment was ever made.
During, Iași was the capital of a much reduced Romania for two years, following the ' occupation of Bucharest on 6 December 1916. The capital was returned to Bucharest after the defeat of and its allies in November 1918. In November–December 1918 Iași hosted the. Jewish community. (1671) In 1855, Iași was the home of the first-ever -language newspaper, Korot Haitim, and, in 1876, the site of what was arguably the first-ever professional performance, established. The words of, the national anthem of, were written in Iași. Jewish musicians in Iași played an important role as preservers of Yiddish folklore, as performers and composers.
According to the 1930 census, with a population of 34,662 (some 34% of the city's population), Jews were the second largest ethnic group in Iași. There were over 127. After, in 1947, there were about 38,000 Jews living in Iași.
Because of massive emigration to Israel, in 1975 there were about 3,000 Jews living in Iași and four synagogues were active. Currently, Iași has a dwindling Jewish population of ca. 300 to 600 members and two working synagogues, one of which, the 1671, is the in Romania. World War II. Main articles: and In May 1944, the Iași area became the scene of ferocious fighting between Romanian- forces and the advancing and the city was partially destroyed.
The German won a defensive victory at the, near Iași, which was the object of several studies during the. By 20 August, Iași had been taken by Soviet forces. Post-World War II era Iași experienced a major wave of industrialisation, in 1955–1975. During this period of time, it received numerous migrants from rural regions, and the urban area expanded. The saw a growth of 235% in population and 69% in area in Iași; however, the urban planning was sometimes arbitrary and followed by dysfunctions. By 1989, Iași had become highly industrialised, with 108,000 employees (representing 47% of the total workforce) active in 46 large, in various industries: chemical, pharmaceutical, metallurgical, heavy equipment, electronics, textile, food, energy, building materials, furniture.

Each year, around 14 October, hundreds of thousands of pilgrims gather to commemorate Saint Parascheva, while the city itself established its Celebration Days at the same time. The October pilgrimage is one of the largest in Europe, drawing people all over Romania as well as from neighboring Orthodox countries. During the entire year, pilgrimages to Iași can also involve visits to a large number of religious sites, both within and around the city. Gardens, parks and natural landmarks.

The new old Ping Eye 2 irons February 4, 2012I recently acquired (thank you, DJC) a set of Ping Eye 2 irons. I’ve pretty much determined (by comparing the various patent numbers, serial numbers and other marks in the cavity of the iron) that these are a set of the 1985-1990 Eye 2s, the ones with the square grooves that have been ascribed magical properties by some.
(I’m not sure what kind of tolerance this audience has for the kind of Dan Aykroyd-esque technical discussions I’m some given to engaging in, so if you want a detailed history of the Ping Eye 2s and the “square groove” controversy, you might want to Google the terms, or go.)Anyway, although the Eye 2 is allegedly the most popular iron ever manufactured, I didn’t have any experience with them prior to acquiring this set. There are a couple of reasons for this — when I started plating in the early 1970s, I started out playing hand-me-downs from my father, which meant I started out playing forged blades (because that was pretty much all there was). The first set I remember that I thought of as my own was a set of Shakespeare blades with, believe it of not, fiberglass shafts. (A lot of you probably won’t believe it, so.)As I grew and got better, I played a set if Ben Hogan Directors, MacGregor Tourney Custom, and ultimately a very clean a Wilson Staff Tour Blade set that came with me to college.I quite playing around 1984 — a couple of years after the Ping Eye 2s were introduced — and at some point still undetermined but probably around 1987 someone (possibly my brother-in-law) other than myself took possession of the W/S set.
I have a vague fear that they were sold off in a garage sale.When I returned to golf, at the urging of my beautiful wife, sometime around the end of 1995, she bought me (after months of window shopping and research) a nice set of Titleist OS irons. Those were the first cavity backs I ever owned, and while they were great at easing me back into the game (plenty forgiving), they were like little shovels. It wasn’t long before I felt like I needed a player’s iron.Which led me to my first experience with Ping irons.
When I upgraded, I was fitted for a set of Ping I3 blades.It wasn’t exactly my first experience with Ping, somewhere along the line I’d picked up an old Anser putter. (Still have a number of Ansers in the arsenal, but that’s another post.) But I didn’t know much about the company, though during my layoff from the game, I’d spent a year in Phoenix, where they are headquartered. I even considered an apartment very close to their factory — I drove by it all the time.Still, my memories of Ping from the old days were very weird. When I’d first heard of them, I’d assumed (because of the name, I guess) that they were a Japanese company. And I’d heard that their golf balls (which they only made for a short time) floated in water hazards.
(They didn’t, but there might have been a Japanese make that did — I think that story is apocryphal, but who knows? Anyone?) I thought their clubs were weird-looking.But I had heard so much about them, and I wanted to try something different — and the I3 Blades (which were’t true blades) were about as different as I could stand. I was surprised when they turned out to be about a club longer than what I was hitting — suddenly I could fly a seven iron 170 yards — and they were very straight. I grew quite fond my Ping I3 blades and might still be playing them had they not been stolen (another post for another day).But I shopped around with the with the insurance check in my pocket and tested irons until I found the love of my golfing life, a set of Mizuno blades. I’ve had Mizuno blades — first the MP-14, then the MP-32, and now a mixed set of MP-67 and MP-53s — in my bag ever since. (Not to those of you who know me: Yes, I have dallied with other irons — I had a flirtation with the Taylor Made R9 TP irons, but I never really left Mizuno.
And yes, I do carry a Taylor Made Burner four iron but that’s a crazy club — I consider it a hybrid and hit it longer than I have any five wood.)I love the Mizunos primarily because of their feel. If you don’t know what I’m talking about, you’re probably better off, but I’ve never hit irons that produced that transmitted the sweet crushing sensation of compressing a golf ball better. I’d play Mizuno even if I knew I could score slightly better with another set, because playing slightly better doesn’t mean a whole lot to me. I’m probably as good at the game now as I’ll ever be (and I may be as good now as I’ve ever been).I say that, but having fooled around a bit with the Eye 2s, I think I get it.These are amazingly solid, stable clubs, and while the hitting sensation isn’t the same as with a forged blade, it’s very satisfying. And the short irons and the wedge (which has 52.5 degrees of loft, which makes it weaker than the gap wedge I’m carrying now) is frankly amazing.
Serial Number
My shots with it were high and mostly they stopped like darts on the green. It was like hitting one of those velcro-strapped whiffle balls — on impact with the green, everything comes to an an abrupt halt.Plus, despite the weaker lofts, I seemed to be hitting the short and mid-irons nearly as far as my Mizunos.The long irons did seem to collapse together — I could hit the Eye 2 four iron about as the Eye 2 three iron, and there wasn’t more than a five yard gap between the five iron and the four iron.
In other words, if I were to actually play the irons, I’d probably use the five iron as my 190 yard club, and the three as my 200 yard club. Currently, my five iron, with it’s admittedly jacked-up loft, is my circa 200 yard club, and I rarely hit the aforementioned TM four iron unless I’m trying to move it 215 or more more yard. (That four iron is amazing — I have hit it 240 off the tee in calm conditions.)But I think I could play very well with the Eye 2s. I could adjust to the feel.
And I already think they’re extremely good-looking.Of course, there are genuine technological advantages to newer clubs, but in truth the differences from year to year are slight. I probably couldn’t play with the Wilson Staff Tour Blades I used to play with — I still have my old Tourney Custom one iron and I find it impossible to believe I ever hit that knife more than 160 yards.But these 25-year-old Eye 2s are remarkably playable. Easier to hit than my clubs, and you get nearly as much out of them at the top end. Were I better, I’d probably like them even more.You can still order a set of brand new Eye 2s from the factory, though they’d agree not to produce them with the so-called “square grooves” anymore. (Though technically the grooves are legal — that’s why, a couple of years ago, after the new “conditions of competition” rules limited the size of grooves on irons, several PGA tour players — including Phil Mickelson, John Daly and Hunter Mahan — briefly started using 20-year-old Eye 2 wedges.).
