Their results included a 6 kV thyristor that can switch 111 kA with an 85 kA/μsec di/dt[11].
WebPhase 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 ... WebThe thyristor device works as a silicon-controlled rectifier (SCR) so it can only conduct current to one direction (see AN4607), while Triac can be considered as two back-to-back …
