Hi! I made a push-pull dc-dc converter which should convert 6.3v from 2 LiFepo4 in series to around 36-40v. I used SG3525. First I used 2+2 IRFB7434 switches, but they were heating up much, then I added more and created 4+4 IRFB7434 switching scheme. Switches and SG3525 are powered from 12v computer power supply. Wave on switches is square - I checked by oscilloscope. I connected gates through 4.7Ohm resistors and with reversed fast diodes in parallel to them. SG3525 circuit has "driver transistors" on it's output- 3A D772 and B882. For transformer core I used TP4A-T42-26-13mm ring. Winding is 4+4 primary and 29 turns of secondary. Rectifier on secondary - full bridge from 4 fast 8A diodes. By playing with frequency I found that optimal frequency for efficiency is around 9kHz. With increasing efficiency - output voltage drops under constant resistive load. I was loading it with 200w load. But even with such powerful mosfets they are heating up fast.... They are mounted on a big heat sink, Also transformer is not heating up much. After 1 minute of load it's only around 30-35 C, same as rectifier diodes are not heating up much too.... And efficiency is only around 75%. Do you have ideas why this may be happening? Maybe mosfets are fake, not original, and have bigger Rdson? Or maybe this core I used here is too big for a 200-300w power? Or maybe is should add some snubber circuits to mosfets and it will help? Or maybe it is notrmal that I have 75% efficiency with such small 6v input voltage for such transistors? (I wish I could reach 85-90% efficiency)....

Awesome Content.

Thank you for sharing your knowledge😊 I have a question can i replace 5w cement resistor 3.9ohm to 4.7o ohm?that will not be couse any damages to PCB board?

Sir does this smps use high side driver or just two low side switching

As far as efficiency of a Push-Pull...is there any advantage to your topology (with a center tap secondary winding and two diodes) as opposed to secondary with no center tap feeding 4 diodes in bridge arrangement? Thanks, Steve

Very very interesting and useful. To choice the right transistor voltage, is it necessary to have a transistor with 900 V tension? Is it right?

@HaseebElectronics

best regards yes transistor voltage must be at least above 2.25 x V in or 2.5 x V in

هل ممكن تُستعمل هذه الطريقة مع أجهزة اللحام أم لا ؟ Can this method be used with welding devices or not?

no. this is not effective design for welding machines. welding machines need "FULL BRIDGE OR H-BRIDGE TOPOLOGY"

How your doing better sir . If you can reply to my question I would be thankful, I rise my frequency to 250khz with a double EE5525 core the core is 1pound in weight but at 250khz the voltage dropping from 200volt to 175 volt is there a bad reason why this happens ,?

sorry for that. i will check it and will try to reproduce it

watch your primary side of your schematic ! Need for a more complex "basic" schematic. The driving unit have to have a Q and a -Q outputs
