A novel three-phase welding inverter power supply with high power factor

Huang Ji-Qiang; Chen Shujun; Yin Shu-yan; Wang Dong-Ping; Zeng Hua

A three-phase welding inverter power supply (WIPS) with power factor correction (PFC) function is proposed to deal with the input current distortion problem that baffled WIPS application for several years. In this paper, a switch-rectifier is used and controlled by a digital signal processor (DSP) based on space vector modulation (SVM) to replace diode-rectifier of the conventional WIPS. The control strategy to realize PFC function in WIPS is studied. A new two-mode work scheme is proposed to overcome the problems brought by switch-rectifier when WIPS work in open-load period. A new WIPS device with PFC function is constructed and experimented to confirm the validity.
