Research on resonant parameters design method of series-parallel resonant capacitor charging power supply

In pulsed power system, capacitor charging power supplies (CCPS) are normally employed to provide energy for capacitor. To meet the request of reducing input power rate, this paper focuses on the series-parallel resonant CCPS. In this paper, the electric characteristic of series-parallel resonant converters is analyzed in detail. Based on theoretical analysis, the resonant parameters design method of series-parallel resonant converters, which contains resonant parameters design and pulse width of drive signal design, was proposed. Simulation verifications and experimental results are carried out to prove the validity of theoretical analysis.
