Capacitor charging power supplies (CCPS) are used for pulsed-power applications such as electromagnetic guns, radar applications, and pulsed lasers for aesthetic medicine, among many other application fields. This paper describes the design and analysis of an Input Parallel Output Series-Phase Shifted Full Bridge converter (IPOS-PSFB) for CCPS. In CCPS application, attaining long-lifetime of the high voltage (HV) pulsed capacitor is critical. The proposed system possesses low output current ripple to improve the lifetime of the pulsed capacitor. With the output voltage not being constant, modifications on the output current ripple equations for selecting an appropriate output inductor parameter is required. The proposed system employs a Constant Current - Constant Power (CC-CP) charging profile instead of a Constant-Current (CC) charging profile. Comparative evaluation of the CC-CP charging profile is presented to elucidate the advantage of employing CC-CP. Circuit simulation and experimental results from a hardware prototype are included to validate the design and to show the effectiveness of the proposed system. |
