Improvement of a high repetitive rate static impulse voltage generator

Summary form only given, as follows. We have developing a high repetitive rate static impulse voltage generator (static IG) where closing switch of each stage is composed of a power thyristor (Thy) switch and its gate circuit which automatically functions as a result of turn-on of the first stage Thy switch. Each stage capacitor of IG is quickly charged (within 100 micro sec.) through bypass of diodes to the voltage controlled by the charging period signal. And we have demonstrated its high repetitively (more than 2 kHz) and efficient charging property (above 90%). In this paper we present improved static IG with new mechanism for gate circuit which expand its adjustment width, whereas it is difficult to regulate former gate circuits because it functions by the anode-cathode voltage increment of Thy through high pass filter circuit. As a consequence of low impedance charging method, the new gate circuit is triggered by voltage signal without filters and does not mis-operate in the charging period.
