變頻技術(shù)誕生背景是交流電機(jī)無級(jí)調(diào)速的廣泛需求。傳統(tǒng)的直流調(diào)速技術(shù)因體積大故障率高而應(yīng)用受限。
變頻器
20世紀(jì)60年代以后，電力電子器件普遍應(yīng)用了晶閘管及其升級(jí)產(chǎn)品。但其調(diào)速性能遠(yuǎn)遠(yuǎn)無法滿足需要。1968年以丹佛斯為代表的高技術(shù)企業(yè)開始批量化生產(chǎn)變頻器，開啟了變頻器工業(yè)化的新時(shí)代。
20世紀(jì)70年代開始，脈寬調(diào)制變壓變頻(PWM－VVVF)調(diào)速的研究得到突破，20世紀(jì)80年代以后微處理器技術(shù)的完善使得各種優(yōu)化算法得以容易的實(shí)現(xiàn)。
20世紀(jì)80年代中后期，美、日、德、英等發(fā)達(dá)國家的 VVVF變頻器技術(shù)實(shí)用化，商品投入市場，得到了廣泛應(yīng)用。 最早的變頻器可能是日本人買了英國研制的。不過美國和德國憑借電子元件生產(chǎn)和電子技術(shù)的優(yōu)勢，高端產(chǎn)品迅速搶占市場。 相比較國外變頻器的發(fā)展?fàn)顩r，我國的變頻器應(yīng)用起步較晚，直到20世紀(jì)90年代末期才得到較為廣泛的推廣。國內(nèi)變頻技術(shù)發(fā)展?fàn)顩r，可以概括為：變頻器的整體技術(shù)相對落后，和國外在變頻調(diào)速研宄上取得的先進(jìn)成果比，存在著較大的差距；變頻器使用的核心部件技術(shù)空白，目前來說，變頻器的生產(chǎn)中需要的關(guān)鍵功率器件，在國內(nèi)幾乎沒有廠家可以生產(chǎn)，導(dǎo)致我們核心技術(shù)受制于國外，必須依靠進(jìn)口；主要產(chǎn)品集中在低壓產(chǎn)品和中低端市場。由于產(chǎn)品可靠性和工藝水平不高，目前國內(nèi)變頻器產(chǎn)品主要面向低壓和對性能要求一般的市場，高性能、大功率市場主要被國外大公司占領(lǐng)。
步入21世紀(jì)后，國產(chǎn)變頻器逐步崛起，現(xiàn)已逐漸搶占高端市場。上海和深圳成為國產(chǎn)變頻器發(fā)展的前沿陣地。
