Hello sir, i have made same circuit it's only working with 14+14 turn nd 250 turn, when i rewind ferrite core 3.0.3 turn it's not working and mosfet heating
Hello dear sir please reply quickly as possible, I have made same circuit design but my circuit is not working, sg3525 outputs giving 5vots pin 11/14 but when connected to MOSFET gates with 20ohm, it's immediately shorting the MOSFET and sg3525 damaged, the transformer is 3+3 turn/ 80 turns, i have damaged more then 10 sg3525 and lot's of mosfet
After building this circuit use serial bulb to check the no load current ,while the bulb is glow full brightness then you would need to fix the issue in you circuit until the serial bulb brightness get decreases
