摘要
介绍一种晶闸管调功器,用集成运算放大器组成的变周期调制电路和由时基电路组成的晶闸管触发器。它具有线路简单、成本低、稳定可靠等优点。同时亦介绍了电路不采用电源变压器直接接至电网的实现方法。
A sort of thyristor power adjustor is introduced including the modulation circuit with varying cycle and thyristor triggers which are consisted of integrated operational amplifier and time-base circuit respectively. It has simply circuits, low cost and is stable and reliable. The paper also gives a circuit direct coupling to power supply without transformers.
