The logical design of resonant parameters and the high frequency high voltage transformer was adopted and the power density of 0.5 MW/m3 was achieved. The protection technology of the CCPS was studied, and the performance of the CCPS was improved by using multiple protecting techniques and safeguards. A scheme of remote control and parallel operation of the power supply was introduced. Some experimental results were given with a 1 MJ/10 kV capacitive load.
