摘要

根据实际电机试验工程应用，对变频调速系统中，变频器封锁脉冲后，输出LC滤波器中的电容器与高速运行的异步电机之间产生的自激现象进行分析，提出了抑制自激现象的方法。仿真和实际工程应用验证了自激抑制措施的可行性。

Abstract

Based on the actual motor test engineering applications, self-excitation phenomenon between capacitor of LC filter and rotating asynchronous motor was analyzed when inverter suddenly blocks pulses for frequency control system, as well as methods for suppressing self- excitation were proposed. Simulation and practical applications proved the feasibility of the methods.
