为解决传统晶闸管触发装置的一系列问题，设计了一种新型PWM脉冲控制的晶闸管触发装置。该装置由5个部分构成：晶闸管双向电子开关、负载、过零脉冲产生及直流稳压单元、触发信号产生单元、控制信号给定单元。双向晶闸管作为双向电子开关，CMOS非门作为移相控制单元的核心器件，其阈值电压直接作为触发基准电压，利用PWM信号进行移相控制。测试结果表明，该装置具有较好的抗干扰性能和良好的移相控制线性度，且成本低，体积小，工作稳定可靠。

In order to solve a series of problems of traditional thyristor trigger device, a new thyristor trigger device controlled by PWM pulse was designed. The device consisted of five parted of two-way thyristor electronic switches, load, zero pulse generation and DC voltage unit, trigger signal generating unit and control signal given unit. Taking the bidirec-tional thyristor as two-way electronic switch, CMOS not gate as the core of phase shift control unit and its threshold voltage directly as the trigger reference voltage, applied PWM signal to phase shift control. The experimental results show that the device has strong anti-interference ability, good phase shift control linearity, which is low cost, small volume and works reliably.
