摘　　要：在建立PWM逆变器 电缆 电机高频模型基础上 ,通过仿真电机端子上的PWM脉冲反射波瞬间电压 ,建立了反射波峰值电压与电缆长度之间的关系 ,并给出不同电缆长度情况下电机端电压的仿真及实验波形。The high frequency model in this paper contains the inverter cable motor.With simulating the reflected wave transient voltage impressed on ac induction motor, the relation between the over voltage and cable distance is established. By changing cable distance, the motor terminal voltage wave based on the Matlab simulation is presented. Lastly, with altering the length of cables,the measured voltage waves on motor terminal are received.
