一、是一種集軟啟動、軟停車、輕載節(jié)能和多功能保護于一體的裝備。實現(xiàn)在整個啟動過程中無沖擊而平滑的啟動電機，而且可根據(jù)電動機負載的特性來調(diào)節(jié)啟動過程中的各種參數(shù)，如限流值、啟動時間等。
二、（Variable-frequency Drive，VFD）是應(yīng)用與微電子技尸通過改變電機工作電源頻率方式來控制的電力控制設(shè)備。
三、和軟啟動的區(qū)別
1、頻率方面： 的輸出頻率固定為電源頻率，頻率不可調(diào)；是輸出頻率可調(diào)。
2、電壓方面： 通過控制（或其他電力電子元件）導(dǎo)通角來控制輸出電壓，其輸出電壓由0V慢慢升到；變頻器的電壓是可調(diào)的。
3、電機速度方面：

	軟啟動器不可調(diào)節(jié)電機速度；變頻器可以調(diào)節(jié)電機在任何速度運行。
