Abstract :
This paper describes design and implementation of a 60kJ/s capacitor charging power supply with output voltage 50kV, basing on the theoretical, simulating and experimental research of HF AC-Link technology. Designing details of the power supply were reported. The power supply consists of an EMI filter, a matrix switch, a LC resonant bank and a high frequency transformer. A higher power density of above 0.6W/cm3 is achieved with the CCPS, by utilizing various technologies on HF AC-Link topology and proper packaging. The experimental results demonstrate that power-factor of the CCPS is 0.99 higher. The experimental results demonstrate that the converter meets the performance requirements while achieving a high power density.
