摘要
基于高频脉冲下电机端过电压对系统产生的危害,分析了PWM方式供电下的电缆高频模型、电机的低频-高频通用模型,建立了高频PWM下逆变器—电缆—电机的系统仿真平台,验证了电机端过电压影响因素,为进一步的研究提供了参考。
Based on phenomenon of the terminal over-voltage oi induction motor fea by nigh frequency pulse, which will lead to great hazard, the high-frequency module of power cable and universal module of motor are analyzed in the paper. The system simulation platform of inverter-cable-motor fed by high-frequency pulse operation is constructed. Some influence factors on over-voltage of motor have been verified in the simulation platform, which is convenient for further studies on the methods of suppressing over-voltage
