The power system uses a pulse-capacitor power topology scheme combined with theoretical calculations to provide a key guiding solution for actual power supply development. In order to better select the device parameters, the simulation model is built using the PSpice software, and the device parameters satisfying the system requirements are obtained through the response waveform analysis. In addition, the power system has also developed a control system that meets plasma discharge requirements. The control system adopts the communication mode for serial communication, Labview to build the upper computer interface and the FPGA to complete the logic system configuration of the lower computer, and the system is simple and efficient.
