摘　　要：在同步发电机的自动励磁调节装置中,移相触发模块用来触发整流桥中的晶闸管,使其控制角随着发电机端电压的变化而改变,从而达到自动调节励磁的目的,因此移相触发技术是自动励磁调节装置的一项关键技术。在简要介绍自动励磁控制器的主功能和辅功能构成的基础上,较详细地叙述了三相晶闸管数字移相触发电路的各个组成单元的原理、抗扰动技术和脉冲故障检测技术,以及移相触发模块的研究现状,并预测了自动励磁调节装置的发展趋势。In the automatic excitation controllers of synchronous generator, the movable phase trigger circuit is used to trigger thyristor and make control angle change along with the variety of voltage distribution across thyristor in order to adjust excitation,so it is a key technology in automatic excitation controllers. The main function and assist function of automatic excitation controllers was introduced, then recited the theory of all parts of movable three-phase trigger circuit. Finally, it introduced the theory of anti-interference technology and pulse failure detection and tried to figure out the development current of movable phase trigger circuit.
