in UPS i use the PIC to control pulse width modulation for this circuit , i want UPS out put (modulated sine wave) so .. this circuit output square .. you know ?? i want it to out sine using pic .
He doesn't need PWM back in the day thay would use a relay make it vibrate at 60hz use that to feed a step up transformer 12v to 100 use that to power the radio in a car. Then
came the big metal transistors you make a bridge and a oscillator to switch at 60hz you have the same thing but you can't hear it while your radio is playing a song.
You could try PWM on IC1 pin 1.

Hm. Circuit reminds me of an Alternator-battery charge tester / FET destroyer / Random RF generator / FUSE pop tester. No bleed offs on the gates. Brute force TTL or CMOS timing. I believe you have to get those specific FET's at the IDEAL FET store.

I'm sure it will demonstrate those functions just fine.
I don't have the link handy but the schematic appears to be from a Japanese site that featured really overly complex circuits. Like the LED sign with a small PIC and a pair of FPGAs!!
