Teccor® brand Thyristors
AN1003
Introduction Due to high-volume production techniques, Thyristors are now priced so that almost any electrical product can benefit from electronic control. A look at the fundamentals of SCR and Triac phase controls shows how this is possible. Output Power Characteristics Phase control is the most common form of Thyristor power control. The Thyristor is held in the off condition -- that is, all current flow in the circuit is blocked by the Thyristor except a minute leakage current. Then the Thyristor is triggered into an “on” condition by the control circuitry. For full-wave AC control, a single Triac or two SCRs connected in inverse parallel may be used.
