Abstract

Abstract

Aiming at the pulse operating characteristics of voltage-controlled thyristors, a cascadable driving circuit is designed to realize the synchronous opening of multi-stage series-connected voltage-controlled thyristors. Firstly, the circuit topology and working principle is analysed. in which the coupled inductor is used to isolate the driver signal and transfer power to open the switch. Based on Blumlein PFN, an experimental test circuit is built, in which a 6-stage MOS-controlled thyristor is series connected to be the discharge switch. A quasi-square-wave pulse current with an amplitude of 1.958 kA is obtained on a 4 Ω resistor.
