變頻器（Variable-frequency Drive，VFD）是應(yīng)用變頻技術(shù)與微電子技術(shù)，通過改變電機(jī)工作電源頻率方式來控制交流電動(dòng)機(jī)的電力控制設(shè)備。變頻器主要由整流、濾波、逆變、制動(dòng)單元、驅(qū)動(dòng)單元、檢測單元微處理單元等組成。
變頻器主要是靠內(nèi)部IGBT的開斷來調(diào)整輸出電源的電壓和頻率，根據(jù)電機(jī)的實(shí)際需要來提供其所需要的電源電壓，進(jìn)而達(dá)到節(jié)能、調(diào)速的目的。變頻器有很多的保護(hù)功能，如過流、過壓、過載保護(hù)等。隨著工業(yè)自動(dòng)化程度的不斷提高，變頻器也得到了非常廣泛的應(yīng)用。
