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...

Thanks I am not after credit from that forums. Or we made SMPS to get credit from them. its more than enough for me the people...

thanks so much Sir though to be frank i still cannot relate it to how i use a 0.5mm diameter of wire for primary and 1.4mm for the...

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

I will try different configurations as I have less than 5 IRS2153D left, thanks for the instructions,if have anything news,I'll reply...

hello sir raymond1 you should try any toroidal core with 0.5OD or 1cm OD primary 3&4 single 1mm wire 1turns,secondary 1&2 Wind 50...

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, Silvio I'm Benny from Taiwan, I try to D.I.Y Class D SMPS with IR2153(as followed your circuit), it works well in many stages...

I have another concern that mosfet IRF740 is heating a lot even for a primary current of almost 0.21A (which i calculated from voltage...

Thanks a lot for quick reply. :). i was just trying to avoid increasing sense resistance preoccupied by the idea of heat losses without...
