High Voltage Generation and Ripple Suppression Design of 22kV Switching Power Supply

The high voltage generation mode and ripple suppression of 100kHz switching power supply are studied in this paper. The structure of the power supply system is designed by the power supply simulation software Simplis, two kinds of power supply system structures are built by the single secondary winding transformer and the multiple secondary windings transformer respectively, and the ripple suppression design of their output high voltage is simulated and analyzed. The simulation results show that the low-pass characteristic of RC integrating circuit can be used to filter the high-voltage ripple, which can effectively suppress the ripple and improve the stability of the power supply.
