can i use irfp250n alternative irfp250??please help
Dunno. Need to see a circuit and application.
Yes, they'll work, but you'll need to heatsink them well.
Can you simulate the circuit on computer ? Because I tested that circuit and it doesn't work, SOMETHING WRONG ?
It'll be very fussy about the way you wind the transformer. Make sure you do it rigth
I used diode 1N4007 , and 3 resistor 220 ,100, and 150 5 watt to combine them to 470 ohm 5 watt
Yes. I've tried it before at twelve volts, but i didn't take it any higher with fear of frying my expensive IRFP460's. You can run a ZVS driver with IRF540's at 12V and even at 24V for a bit (they blew up on me).
