Development of high power capacitor charging power supply for pulsed power applications

Abstract

High power capacitor charging power supply (CCPS) using a series resonant converter technology has been developed. The CCPS adopted a 33 kHz IGBT series resonant inverter and a high-efficiency, high-voltage transformer. The performance test of the CCPS was carried out with a 33 nF load capacitor at 40 kV output voltage and 1 kpps repetition rate. Peak power rate of 38 kJ/s and efficiency of 80.4% were obtained.
