Abstract :
To improve the input current waveform and get high power factor, PWM rectifier is extensive used in power system. However, PWM rectifier is working in switch mode and generating great amounts of interference. Based on the switch function, the UM (differential mode) noise source of PWM VSR is obtained. In addition, a direct calculation in frequency domain is proposed for characterizing the interference. The experiment results proved the validity of the proposed method
