Hello I have used 20N60 to generate spwm and it worked well 2 weeks ago
I've left the circuit and rework on it but now it doesn't allow the high frequency although it worked the last time but now the o/p is a square wave not spwm wave
In other words it doesn't allow high frequency to go
it's for the 4 IGBT in the bridge anybody have an idea ?
This is the o/p to weeks ago
