摘要
基于反射理论分析了长线电缆传输感应电机系统过电压的原因,通过电缆模型得出了RC滤波器的基本设计方法,然后建立了从PWM逆变电源、电缆到电机的传动系统模型。仿真和实验验证了理论分析的正确性。
Based on reflection theory, the cause of over voltage of induction motors transmitted by long cable is analysed. The fundamental design method of RC filter is obtained through the cable model. Then the driving system model from PWM inverter power supply, cable to motor is established. Simulation and experimental results verify the correctness of theoretical analysis.
