摘　　要：设计了一种基于单片机的数字晶闸管触发器的硬件与软件,它能够根据键盘输入的触发角和同步信号产生相位合适的双窄脉冲触发信号,经功率放大驱动三相桥式全控整流电路的晶闸管,同时显示触发角。在DKSZ-3型电力电子实验装置上,调试了触发器。The hardware circuit and controlling software for a new digital trigger circuit for thyristor power regulator are designed based on single-chip microcomputer.It can generate appropriate double-pulse triggering signals according to trigger angel which is supplied by keyboard and synchronizing signals.It is displayed by the crystalcartridge tube with three-phase full-bridge controlled rectifier circuit which is drived by amplifying power.The digital trigger circuit has been debugged on DKSZ-3 power electronic experimental.
