浅析三相交流异步电动机电子软启动器
Thus , an open loop control scheme and a closed loop control scheme based on chopper system are introduced . lastly , a hardware and software design based on m icro - controller is presented
本文最后对基于斩波方式的三相交流异步电动机的软起动方法给出了基于远程监控的具体实现方案。
To reduce the high starting current as asynchronous motors start up directly and eliminate the negative influence that brought about by switching of contact when it starts up with reduced - voltage means , two new methods based on power electronics technology for improving the starting characteristics of three - phase induction motor are presented . one is alternative voltage regulator , the other is alternative voltage chopper . the three - phase regulating circuit - asynchronous motors system and the three phase chopper circuit - asynchronous motors system are analyzed and simulated with matlab
为解决上述问题，本文提出一种基于斩波方式的三相交流异步电动机的软起动新方法，论文对电路的起动特性、功率因数、谐波以及控制策略进行了研究，仿真结果表明这种基于斩波方式的三相交流异步电动机的软起动方法比基于三相交流调压的三相交流异步电动机的软起动方法具优越性。
