In Chapter 2, we considered various methods for triggering SCRs. Of these, the most efficient method for power modulation with thyristors uses gate control. In AC circuits, the SCR can be turned on by the gate at any angle α with respect to the applied voltage. This angle α is the firing angle. Power control is obtained by varying the firing angle, and this is known as phase control.
