軟起動器是一種集電機(jī)軟起動、軟停車、輕載節(jié)能和多種保護(hù)功能于一體的新穎電機(jī)控制裝置，國外稱為Soft Starter。它的主要構(gòu)成是串接于電源與被控電機(jī)之間的三相反并聯(lián)閘管及其電子控制電路。 運(yùn)用不同的方法，控制三相反并聯(lián)閘管的導(dǎo)通角，使被控電機(jī)的輸入電壓按不同的要求而變化，就可實(shí)現(xiàn)不同的功能。
　　軟起動器和變頻器是兩種完全不同用途的產(chǎn)品。變頻器是用于需要調(diào)速的地方，其輸出不但改變電壓而且同時(shí)改變頻率；軟起動器實(shí)際上是個(gè)調(diào)壓器，用于電機(jī)起動時(shí)，輸出只改變電壓并沒有改變頻率。變頻器具備所有軟起動器功能，但它的價(jià)格比軟起動器貴得多，結(jié)構(gòu)也復(fù)雜得多。
