Optimal design of high-efficiency series resonant capacitor charging power supply

The series resonant capacitor charging power supply is the most important part of the pulse plasma thruster, so research work is carried out for its development process and parameter optimization design. Compared with previous related studies, this article clearly analyzes and points out the key parameters that affect the charging speed and efficiency of the capacitor, namely the switching frequency and driving pulse width, and gives their optimal solution instead of the previous range. Therefore, the research has certain reference value for optimizing the design of the series resonant capacitor charging power supply, improving the performance of the power supply, and selecting the device reasonably.
