摘要
该数字触发器由TP801及扩展的接口电路构成,能提供两路触发脉冲,皆为同一给定控制。控制可控整流桥的触发脉冲移相范围为30°～90°,控制无源逆变桥的触发脉冲调频范围36～360Hz,可使逆变桥输出电压频率在6～60Hz可调。调频调压的配合考虑了低频时电压补偿的问题。
The digital trigger is constituted by TP801 and expending interface circuit. It can supply two pulse groups which are controlled by same order. Regulated range of pulse for silicon-controlled rectifier is 30°- 90°. Frequency range of regulated pulse for reverser is 36-360 Hz. It can make the frequency of output voltage regulated in range of 6-60 Hz. In coordination of ranging frequency and voltage, voltage compensation of low frequency is considered.
