Abstract：This paper proposes a resonant parameter design method and fuzzy control strategy for the charging current of high-voltage capacitor charging power supply, based on the phase-shifted series resonant converter (PS-SRC). Phase-shifted modulation scheme is employed to run the series resonant high-voltage capacitor charging power supply under over-resonance and continuous current modes. The electric characteristics and boundary conditions of three PS-SRC operation modes are analyzed and derived. And then, the operation mode is analyzed in detail by the numerical method, which is suitable for capacitor charging application. To meet the application requirements of high-voltage capacitor charging power supply, the design method of resonant parameters is proposed. Moreover, because it is hard to derive the precise mathematical model of PS-SRC, fuzzy control strategy of charging current is proposed, and the design method of fuzzy controller is presented. Finally, the experimental results verify the validity and feasibility of the resonant parameter design method and the charging current control strategy.
