摘要
本文采用波理论分析变频驱动系统中高频PWM波反射,采用MATLAB仿真软件搭建软件模型,分析变频器输出电压波形的上升下降时间、供电电缆的长度、供电电缆分布参数及系统负载大小对电机前端过电压产生的影响,总结出高频PWM波反射对电机端过电压的影响。
Using the wave theory, high-frequency PWM wave reflection in a inverter drive system is analyzed. Software model is built by using of MATLAB simulation software. It analyzes and summarizes the effect of some parameters on the over-voltage of the motor＇s front-end. This parameters includes the rise and fall time of the waveform, the length of power cables, the distribution parameters of power cables and the system load.
