Abstract
To drive a magnetron injection gun, thsi paper decribes a design, fabrication and analysis results of proposed compact capacitor charging power supply (CCPS) formed resonant full-bridge inverter for electron gun power supply (EGPS). EGPS needs the -40 kV output voltage and 280 kW output power for few seconds continuously and have to be designed for the rise and fall time to be less than 1 ms with the ripple stability of output voltage of lower than 1%. In order to meet the requirements, we used eight resonant full-bridge modules operated in parallel. Each resonant full-bridge module can supply the current of 0.9 A and the voltage of 40 kV, and is operated by N-phase shift switching pattern. In this paper, we present the design, simulation and test results of interleaved CCPS.
