摘　　要：针对三相弧焊逆变电源功率因数校正技术特点 ,提出了基于PWM整流器的弧焊逆变电源PFC的新方案 ,并对PWM整流器模型进行了分析和研究 。Low input power factor and distortion of input current are undesirable in arc welding inverter with diode rectifier. In this paper, three phase pulse width modulation (PWM) rectifier is introduced into the power factor correction (PFC) of arc welding inverter. Analysis is done to study the model of PWM rectifier. Simulations and experiments are discussed to confirm that the new method is a feasible way to deal with the above mentioned problems.
