You relate power in the input and power in the output according to the voltage in each case. Volts per turn Pri = 320v / 30 = 10.7v per...

This is how I feed the IR2153 without heating anything.

Regarding the 13v zener burning it is not normal because at 4 turns in the auxiliary winding the output voltage here is around 18 to...

Hi Benny, be careful that you are not using IRS 21531 as this IC has a shorter dead time only 0.6uS compared to the IR 2153 which is...

Hi Saqib, I think you are missing something here. Let us consider your forward converter. So the power to be absorbed by this forward...

The assumption is not right. You have to consider power input versus power output and adding around 20% more on the input to cover...

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...
