Abstract
This article introduces the principle of the thyristor switched capacitor and the requirement for a fast zero trigger.The characteristics and the existed problems of two types of trigger circuits for thyristor were analyzed.A circuit frame diagram for a newly designed mechanism of acquiring the zero thyristor voltage signal from the thyristor in the main closed circuit is plotted.Based on this circuit
a series of trigger circuits were generated and excellent trigger effects were achieved.
