  电子技术包括信息电子技术和电力电子技术两大分支。通常所说的模拟电子技术和数字电子技术都属于信息电子技术。电力电子技术是应用于电力领域的电子技术。具体的说,就是使用电力电子器件对电能进行变换和控制的技术。所用的电力电子器件均用半导体制成,故也称为电力半导体器件。电力电子技术所变换的“电力”,功率可以大到数百MW甚至GW,也可以小到数W甚至1W以下。信息电子技术主要用于信息处理,而电力电子技术则主要用于电力变换。电力电子涉及由半导体开关启动装置进行电源的控制与转换领域。半导体整流控制、半导体硅整的小型化等的出现,产生一个新的电力电子应用领域。半导体硅整流、汞弧整流器应用于控制电源,但是这样的整流回路只是工业电子的一部分,对于汞弧整流器应用范围而言是有局限的。半导体硅整流的应用涉及很多领域,如汽车、电站、航空电子、高频变频器等。 Electronic information technology,     including electronic technology and power electronics technology two branches. Commonly referred to as analog electronics and digital electronics are all electronic information technology. Power electronics technology is used in power electronics field. Specifically, it is the use of power electronics and control of electric energy conversion technology. Used in power electronic semiconductor devices are made, it is also known as power semiconductor devices. Power electronics technology transformation "power", the power can be as large as several hundred MW or GW, may be as small as a few W 1W or less. Electronic information technology is mainly used for information processing, and power electronics technology is mainly used in power conversion. Control and power electronics involves converting the field from the semiconductor switching device to start power supply. Miniaturization of semiconductor rectifier control occurs, the entire semiconductor silicon, creating a new power electronic applications. Semiconductor rectifier, mercury arc rectifiers used to control the power, but only a part of such a rectifier circuit of industrial electronics, mercury arc rectifiers For application range is limited. Semiconductor rectifier application involves many fields, such as automotive, power plant, avionics, high frequency inverters.
