电路如三相全控桥式整流电路。使用软启动器启动电动机时,晶闸管的输出电压逐渐增加,电动机逐渐加速,直到晶闸管全导通,电动机工作在额定电压的机械特性上,实现平滑启动,降低启动电流,避免启动过流跳闸。待电机达到额定转速时,启动过程结束,软启动器自动用旁路接触器取代已完成任务的晶闸管,为电动机正常运转提供额 定电压,以降低晶闸管的热损耗,延长软启动器的使用寿命,提高其工作效率,又使电网避免了谐波污染。软启动器同时还提供软停车功能,软停车与软启动过程相反,电压逐渐降低,转速逐渐下降到零,避免自由停车引起的转矩冲击。

变频器是用于需要调速的地方,其输出不但改变电压而且同时改变频率;软起动器实际上是个调压器,用于电机起动时,输出只改变电压并没有改变频率。变频器具备所有软起动器功能,但它的价格比软起动器贵得多,结构也复杂得多。电动机软起动器是运用串接于电源与被控电机之间的软启动器,控制其内部晶闸管的导通角,使电机输入电压从零以预设函数关系逐渐上升,直至启动结束,赋予电机全电压,即为软启动,在软起动过程中,电机起动转矩逐渐增加,转速也逐渐增加
