三相整流器移相触发电路的EDA设计

The EDA Design of Digital Phase-shifted Trigger Circuit for Three Phase Full-controlled Rectifier

介绍一种数字移相晶闸管触发电路 ,采用CPLD器件进行编程制作。该电路体积小 ,稳定性好 ,无需调整相序 ,适用于三相全控整流、逆变。

A digital phase shifted thyristor trigger circuit is introduced in this paper.The circuit has small volume and high stability because it is designed by software programming in a programmable logic device.The dircuit doesn't need phase sequence adjusting and is suitable for three phase fully controlled rectification,inversion and voltage regulation etc.,where the double pulse string for triggering is need.
