A SERIES RESONANT SWITCHING CHARGING CIRCUIT FOR KICKER MODULATOR AND ITS SIMULATION STUDY

A novel high voltage charging circuit specially designed for the prototype kicker modulator of the Hefei Light Source storage ring was presented. Zero current series resonant switching techniques and a simple charging voltage control scheme was adopted in the circuit. Simulation model was established to study the performance of the circuit with a high voltage capacitor load. Designed charging voltage stability and repetition rate can be achieved through simulation analysis. Methods to increase the repetition rate are discussed.
