Research on Differential-Mode Conducted EMI of Three-Phase PWM Rectifier AC Side
Taking three phase PWM rectifier as the research object, according to interference mechanism of the rectifier bridge, this paper describes the equivalent circuit of AC side differential mode interference and calculates the interference source voltage and differential mode interference voltage of the three phase PWM rectifier AC side in 150KHz-30MHz frequency band. Then we analyze the model of the equivalent circuit diagram using the Saber software and verify the validity of the model and the accuracy of the calculation through experiments.
