I v characteristics of thyristor
WebBoth the thyristor and triac can be used to control lamps, motors, or heaters etc. However, one of the problems of using a thyristor for controlling such circuits is that like a diode, the “thyristor” is a unidirectional device, meaning that it passes current in one direction only, from Anode to Cathode.. For DC switching circuits this “one-way” switching characteristic … WebApr 9, 2024 · Ⅲ Thyristor I-V Characteristics Curves. thyristor I-V characteristics curves. 3.1 Thyristor turn-on. The gate signal loses all control once the thyristor is turned "ON" and passing current in the forward direction (anode positive). This is due to the regenerative latching action of the two internal transistors.
