半导体以晶体二极管和三极管的形式已广泛地用于整流,电子放大,通讯及计算等等迴路,但是关于它们代替电子管,磁放大器和二极充气管来对电力进行调整控制的应用方面,过去很少提到,现在来谈一下这方面的几种方法,尤其着重它们在直流电压及电流调节上的应用。 Semiconductors have been widely used in the form of crystal diodes and triodes for circuits such as rectification, electronic amplification, communication, and calculations. However, in the past, they used electronic tubes, magnetic amplifiers, and dipoles to control power. Less mentioned, now to talk about several ways in this regard, with particular emphasis on their application in DC voltage and current regulation.
