How to turn off triac
Did you know?
WebFor low apparent motor voltages (long turn on delays), the turn off lag doesn't matter since the triac turns off before you attempt to turn it on again near the end of the next half cycle. As you turn up the motor drive, and therefore decrease your turn on delay, eventually the inductor zero current occurs after your turn on signal for the next half cycle.
