電子技術是十九世紀末到二十世紀初開始發(fā)展起來的新興技術，二十世紀發(fā)展最迅速，應用最廣泛，成為近代科學技術發(fā)展的一個重要標志。在十八世紀末和十九世紀初的這個時期，由于生產(chǎn)發(fā)展的需要，在電磁現(xiàn)象方面的研究工作發(fā)展得很快，1785年法國科學家?guī)靷愑蓪嶒灥贸鲭娏鞯膸靵龆伞?895 年，荷蘭物理學家亨得里克·安頓·洛倫茲假定了電子存在。1897年，英國物理學家湯姆遜（J.J.Thompson）用試驗找出了電子。1904年，英國人J.A.Fleming 發(fā)明了最簡單的二極管(diode或 valve)，用于檢測微弱的無線電信號。 1906 年，L.D.Forest 在二極管中安上了第三個電極（柵極，grid）發(fā)明了具有放大作用的三極管，這是電子學早期歷史中最重要的里程碑。1948 年美國貝爾實驗室的幾位研究人員發(fā)明晶體管。1958 年集成電路的第一個樣品見諸于世。集成電路的出現(xiàn)和應用，標志著電子技術發(fā)展到了一個新的階段。
電子技術研究的是電子器件及其電子器件構成的電路的應用。半導體器件是構成各種分立、集成電子電路最基本的元器件。隨著電子技術的飛速發(fā)展，各種新型半導體器件層出不窮。現(xiàn)代電力電子技術的發(fā)展方向，是從以低頻技術處理問題為主的傳統(tǒng)電力電子學，向以高頻技術處理問題為主的現(xiàn)代電力電子學方向轉變。電力電子技術起始于五十年代末六十年代初的硅整

流器件，其發(fā)展先后經(jīng)歷了整流器時代、逆變器時代和變頻器時代，并促進了電力電子技術在許多新領域的應用。八十年代末期和九十年代初期發(fā)展起來的、以功率MOSFET和IGBT為代表的、集高頻、高壓和大電流于一身的功率半導體復合器件，表明傳統(tǒng)電力電子技術已經(jīng)進入現(xiàn)代電力電子時代。
