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.

With the development of power electronics，the technology of Switching Mode Power Supply(SMPS) is gradually perfected. However，there is no end to the demand for a high power and high performance power supply. Nowadays, Power Factor Correction (PFC) technique is widely researched. This paper mainly analyzes the fundamental configuration of the switching power supply. And we study the basic structure and the operating principles of ZVT-boost soft-switching PFC circuit and the implementing principle of soft switch. For the power requirements, the two-stage PFC circuit is used. The forward stage is a single-phase Boost Power Factor Correction circuit and the backward stage main circuit is a full-bridge converter with the phase-shifting control soft-switching technique. Finally the simulating analysis is performed to the designed system.

the push-pull switch power is a kind of form in the family. It has the characteristics of good voltage output, high efficiency, the simple circuit and so on. On the design of the push-pull switch power supply, the key and difficult point is the design of switch transformer. Taking the switch transformer of a push-pull switching power supply as the research object and based on the design requirements, this paper aims to realize the calculation of the coil turns in switching transformer. Meanwhile, under the consideration of the skin effect and the proximity effect and the choices of switch transformers wires and the methods of wires winding, the design of switch transformer of the push-pull switch power supply has been completed by circuit simulation and implementation.
