摘　　要：通过对三相交流调压电路以及基于三相交流调压的三相交流异步电动机的软启动方法进行分析,基于三相交流调压的异步电动机软启动系统解决了异步电动机启动时,启动电流过大问题,但存在功率因数低,电流谐波成分大的缺点.提出了以8051单片机为核心智能控制三相交流异步电动机的软启动方法.Through the analysis of three-phase ac voltage regulation circuit and the soft start methods of three-phase ac asynchronous motor based on it, a conclusion can be drawn that the soft start system based on the three-phase ac asynchronous motor solves the problems of large starting current when the asynchronous motor starts, however,there are such problems as low power factor and big current harmonics. Then, the soft start methods are proposed, in which the three-phase ac asynchronous motor was controlled by taking 8051 single chip microcomputer as the core intelligent.
