Improvement of a high repetitive rate static impulse voltage generator

We have developed a high repetitive rate static impulse voltage generator (static IG) where closing switches of each stage are 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. 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 a voltage signal without filters and does not mis-operate in the charging period.
