摘　　要：根据实验教学过程中针对传统电力电子实验触发系统的缺点及触发系统要求提出和设计一种新型的采用单片机控制的触发系统,该系统利用单片机对可控硅的触发系统进行控制,以可控硅的关断来控制交流电,从而实现以简单电路对交流电相位进行准确控制。在实际的教学中效果良好,还对该系统在实际中运用作了一些有益的探索。In the teaching process of experiments, a new type of trigger system, controlled by single-chip computer, has been designed. The new device is greatly impoved on the basis of traditional trigger system of electric power and electronic technology, thus achieving fairly good effect in the practical teaching. The system uses a single-chip computer to control the trigger circuit of silicon controlled rectifier （SCR） ： through the switch between ＂on＂ and ＂off＂, the SCR can have an accurate control of the alternating current phase by a simple circuit. It can be well put into practical use in the teaching process. The paper also attempts to carry out an experimental and useful exploration into the application of the device in practice.
