可控硅触发电路是通过调整可控硅的导通角或周波占空比等技术来实现电气设备的电压电流功率调整的一种电力控制器,研究了几种可控硅触发电路的基本结构、工作原理和工作特性等,结合实验测量讨论了各种触发电路的优缺点。与此同时对实验电路进行了分析,阐明了各器件的工作环境、在电路中的作用,说明了操作方法和注意事项。最后,通过实验测得这几种触发电路的输出波形,并对实验结果进行了分析,为今后物理实验的教学提供依据。

The Analysis and the Comparisons on the Performance of Trigger Circuit

Thyristor trigger circuit is a kind of power controllers which adjusts the voltage,the current and the power of electrical equipment via adjusting the conduction angle or the duty cycle.This paper studys the relative merits of different kinds of thyristor trigger circuits.Meanwhile,it analyses the circuits of the experiments,clarifies the working environment and the fuctions of different components.Finally,we get the output wave of these thyristor trigger circuits in experiment.The analyses of experimental result would provide reference for further teaching.
