A capacitor charging power supply for pulsed power generators has been developed with a forward-type single chopper geometry. GaN-HEMT (TPH3206) and SiC-MOSFET (SCT2120AF) as a next generation power semiconductor switch have been compared for high speed switching device of single chopper. In addition, cobalt-based amorphous (FS32) and nanocrystalline soft magnetic material (FT-3M) have been compared as a toroidal core for pulsed transformer. In this work, capacitor charging power supply has been constructed on circuit simulator and universal board. In both simulation and experiment, TPH3206 has shorter capacitor charging time up to 1000 V than SCT2120AF. In addition, FT-3M was able to charge capacitor up to 1000 V faster than FS32.
