In PWM system, the reflected voltage in the cable transmission process generates overvoltage and damps high-frequency ringing at motor terminals and further stresses the motor insulation, even leads to insulation breakdown in premature period. Firstly, in this paper, the cable equivalent mathematical model was established based on three-phase cable. Then the propagation velocity, the oscillation frequency and the oscillation duration of the pulse in the cable was described by mathematical method, and the effects of cable parameters on over-voltage at motor terminals was analyzed under the conditions of high-frequency. Secondly depending on the simulation by PSpice software, we tested and verified the conclusion by building simulation models.
