With an ac voltage applied to the circuit, the gated thyristor (SCR, TRIAC , etc.) remains in its , logic circuits and microprocessors to easily control ac power with TRIAC drivers of both the , control applications. PHASE CONTROL WITH THYRISTORS The most common method of electronic ac power control , accomplishing phase control is shown in Figure 6.2. The electronic switch in this case is a triac (Q) which can be turned on by a small current pulse to its gate. The TRIAC turns off automatically when the current
