A constant current high voltage capacitor charging power supply for pulsed power applications

This paper describes a power supply for a rapid pulsed power charging system designed for charging a 0.25 /spl mu/F capacitor up to 20 kV in approximately 3 ms. It is capable of charging the load capacitor at repetition rate of 300 pps. This power supply is based on a series resonant three phase inverter followed by step-up transformers. Experimental results carried out at different repetition rates and charging voltage are included along with the system descriptions.
