电子技术是十九世纪末到二十世纪初开始发展起来的新兴技术，二十世纪发展迅速，应用广泛，成为近代科学技术发展的一个重要标志。在十八世纪末和十九世纪初的这个时期，由于生产发展的需要，在电磁现象方面的研究工作发展得很快，1785年法国科学家库伦由实验得出电流的库仑定律。1895 年，荷兰物理学家亨得里克·安顿·洛伦兹假定了电子存在。1897年，英国物理学家汤姆逊（J.J.Thompson）用试验找出了电子。1904年，英国人J.A.Fleming 发明了简单的二极管(diode或 valve)，用于检测微弱的无线电信号。 1906 年，L.D.Forest 在二极管中安上了第三个电极（栅极，grid）发明了具有放大作用的三极管，这是电子学早期历史中重要的里程碑。1948 年美国贝尔实验室的几位研究人员发明晶体管。1958 年集成电路的第一个样品见诸于世。集成电路的出现和应用，标志着电子技术发展到了一个新的阶段。

电子技术研究的是电子器件及其电子器件构成的电路的应用。半导体器件是构成各种分立、集成电子电路基本的元器件。随着电子技术的飞速发展，各种新型半导体器件层出不穷。现代电力电子技术的发展方向，是从以低频技术处理问题为主的传统电力电子学，向以高频技术处理问题为主的现代电力电子学方向转变。电力电子技术起始于五十年代末六十年代初的硅整

电子产品

流器件，其发展先后经历了整流器时代、逆变器时代和变频器时代，并了电力电子技术在许多新领域的应用。八十年代末期和九十年代初期发展起来的、以功率MOSFET和IGBT为代表的、集高频、高压和大电流于一身的功率半导体复合器件，表明传统电力电子技术已经进入现代电力电子时代。
