The high side gate drive pin7 gets its power from the bootstrap capacitor. This capacitor charges itself when the lowside mosfet comes...

One other thing I am noticing is that the voltage regulation at pin 1 is all depending on the internal 15v zener inside the chip. I also...

The IR2153 is designed to power medium power mosfets, (10A) however in this circuit the 20n60 mosfets used have a a very low gate charge...

First of all if you intend to build a high current smps, then it has to be prepaired from the design stage. Type of transformer...

Do you have a problem maybe I can help you? Regards, Silvio

Well I also tried my software Excellent IT 7300 at this but as you can see the rated transformer power is far less the the desired...
