Abstract This paper investigated the principle of the PWM pulse wave reflection in the high power induction motor PWM(Pulse Width Modulation) driving system. In order to get the accurate high frequency parameter of the cable and motor, an impedance measuring method for PWM driving system was proposed. The result of the simulation and experiment has proved that the cable and motor high frequency modeling method applied in the voltage reflection analysis can lead to a precise result. The restraint strategy of the voltage reflection by PWM pulse also greatly depressed the over voltage in the motor end.

Key words： Voltage reflection over-voltage long line transmission motor drive
