電子技術是十九世紀末到二十世紀初開始發展起來的新興技術，二十世紀發展迅速，應用廣泛，成為近代科學技術發展的一個重要標志。在十八世紀末和十九世紀初的這個時期，由于生產發展的需要，在電磁現象方面的研究工作發展得很快，1785年法國科學家庫倫由實驗得出電流的庫侖定律。1895 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 發明了簡單的二極管(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）發明了具有放大作用的三極管，這是電子學早期歷史中重要的里程碑。1948 年美國貝爾實驗室的幾位研究人員發明晶體管。1958 年集成電路的第一個樣品見諸于世。集成電路的出現和應用，標志著電子技術發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、集成電子電路基本的元器件。隨著電子技術的飛速發展，各種新型半導體器件層出不窮。現代電力電子技術的發展方向，是從以低頻技術處理問題為主的傳統電力電子學，向以高頻技術處理問題為主的現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，其發展先后經歷了整流器時代、逆變器時代和變頻器時代，并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，表明傳統電力電子技術已經進入現代電力電子時代。
