Hello,
Iam an eletronic engineering student. Iam building a triac dimmer that can dim leading edge and trailing edge (or both).
Currently i have the leading edge working but does anyone know a good circuit for trailing edge? I know a triac turns off on the nullpoint but i need a circuit that can get the current to 0 for a short pulse to turn off the triac while its not on the null point of the sine wave.
Thank you!!
