Aiming at reducing standby power consumption of switching power supply, a low standby power consumption control circuit for switching power supply is designed. The control circuit is composed of power switches, the driving circuit, the load detection circuit and the low power supply circuit. The control circuit effectively closed the input of switching power supply when the switching power supply is without load. The control circuit ensures the normal work of switching power supply when the switching power supply is with load. From the experiment results, the control circuit can effectively reduce standby power consumption of switching power supply.

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.
