WebbPhase 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 ... Webb6 apr. 2024 · It is a three-terminal semiconductor switching device that can be used for fast switching with high efficiency in many types of electronic devices. These devices are mostly used in amplifiers for switching/processing complex wave patters with pulse width modulation (PWM).
