This paper describes the design and implementation of a 60 kJ/s capacitor charging power supply(CCPS)with output voltage of 50 kV, based on the theoretical, simulative and experimental research of high frequency(HF)AC-link technology. Design details of the power supply are reported, which consists of EMI filter, matrix switch, LC resonant bank and HF transformer. A high power density of above 0.6 W/cm3 is achieved with the CCPS, by utilizing various technologies on HF AC-Link topology and proper packaging. The experimental results demonstrate that the power factor and efficiency of the CCPS are higher than 0.95 and 0.90, respectively. In a word, the CCPS features high power density, high power factor and high efficiency.
