We have developed a capacitor charger for 1 kV, 55 mJ/pulse, 5 kpps pulsed power application, which is attainable to 361.8 J/s in average charge power. The charger based on the forward type with two switches consists of topology having the advantage of lower voltage stress, and fast response due to control by a field programmable gate array. The charger is able to accomplish 1.6 µs of a short delay time that mean from the turn-off the inhibit signal to start charging time. Simulation results were applied to the selection of switch devices of laboratory prototype charger of 1 kV, 1 MHz.
