Abstract
In this paper, a novel 10kV, 50A, 50kHz pulsed power supply based on IGBT stacks is proposed. Proposed scheme consists of series connected 12 IGBT to generate maximum 10kV output pulse and 10kW full bridge phase-shifted zero voltage switching converter to charge DC capacitor voltage. Each IGBTs are sustain the 830V of capacitor voltage at turn off interval. By turn on the each IGBT for the same time it gives the path for the series connection of charged capacitor. From above turn on and off procedure, high voltage repetitive pulse is applied to the load. The synchronization of gating signal is important of series operation of IGBTs. For gating signal synchronization, specially designed gate power circuit using full bridge inverter and pulse transformer is developed to generate IGBT gating signal.
