Electrostatic precipitator is the efficient dust removal equipment for environmental protection. As the core part, high voltage inverter power supply determines the efficiency and effect of dust removal. This paper design a high frequency and high voltage switching power supply for electrostatic precipitator based on FPGA. The power supply system is composed of rectifier and filter circuit, high frequency inverter circuit, step-up transformer and high voltage rectifier silicon reactor circuit. Using IRFP460N as power switches, single-phase full-bridge inverter was set up. The SPWM signals produced by FPGA EP2C5T144C8 were isolated and amplified through drive circuit IR2110. The function of variable frequency and voltage was realized. Hardware test showed the whole system operated safely and reliably.

Combination Test

Utilizing a high power discrete SiC-JFET developed by KEK, a switching power supply (SPS) that had a circuit topology of H-bridge was designed and constructed to drive the induction acceleration system for the KEK digital accelerator. The SPS was operated with a 38 Ω dummy resistance load and bipolar outputs of 800V and 21A were successfully demonstrated at 1 MHz. Also, the combination test with an actual accelerator cell is being conducted.
