施耐德 PLC 底板 140XBP01000
軟啟動器采用三相反并聯晶閘管作為調壓器，用這種電路如三相全控橋式整流電路，使用軟啟動器啟動電動機時，晶閘管的輸出電壓逐漸增加，電動機逐漸加速，直到晶閘管全導通，電動機工作在額定電壓的機械特性上，實現平滑啟動，降低啟動電流，避免啟動過流跳閘，將其接入電源和電動機定子之間。
概念編輯
電壓由零慢慢提升到額定電壓，這樣電機在啟動過程中的啟動電流，就由過去過載沖擊電流不可控制變成為可控制。并且可根據需要調節啟動電流的大小。電機啟動的全過程都不存在沖擊轉矩，而是平滑的啟動運行。這就是軟啟動。 [1]
簡介編輯
a新穎電機控制裝置，國外稱為Soft Starter。它的主要構成是串接于電源與被控電機之間的三相反并聯晶閘管及其電子控制電路。運用不同的方法，控制三相反并聯晶閘管的導通角，使被控電機的輸入
電壓按不同的要求而變化，就可實現不同的功能。軟起動器和變頻器是兩種完全不同用途的產品。變頻器是用于需要調速的地方，其輸出不但改變電壓而且同時改變頻率；軟起動器實際上是個調壓器，用于電機起動時，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，但它的價格比軟起動器貴得多，結構也復雜得多。電動機軟起動器是運用串接于電源與被控電機之間的軟啟動器，控制其內部晶閘管的導通角，使電機輸入電壓從零以預設函數關系逐漸上升，直至啟動結束，賦予電機全電壓，即為軟啟動，在軟起動過程中，電機起動轉矩逐漸增加，轉速也逐漸增加。
