I am using "phase-angle-firing" but i just call it PWM since it is PWM that is synced with the zero crossing. Like i said, ive made these kind of circuits before. This circuit is actually based on the last one i made which still works perfectly (i even copied some of the code). The only difference is the last one had the triacs on the same PCB as the chip and transformer and this new circuit has the triacs seperate.
