Webb18 sep. 2024 · Commutation – Turning Off SCR To turn on a thyristor, a low voltage, short duration pulse is applied to the gate (typically 4V, 100µs). Once the thyristor is turned-on, the gate loses control and the thyristor will only turn off when the load current falls virtually to zero, or the thyristor is reverse biased. The thyristor will turn off naturally with A.C. …
