锁相直流调速控制系统的设计与分析

The Design and Analysis of Phase Locked Loop DC Velocity Adjusting Control System

介绍一种锁相型移相触发器,可应用于可控硅三相全控桥变流器供电的直流调速系统中,组成锁相直流调速控制系统,使得三相六脉冲准确地保持60°的间隔,不需要对三相触发脉冲进行平衡调整。

This paper describes a kind of phase locked loop trigger used in DC velocity adjusting system which is supplied with thyristor controlled three-phase full-bridge inverter, and then a phase locked loop DC velocity adjusting control system which could accurately hold sixty degrees distance between the six pulse in the three phase is constituted, additional effort to keep the balance between trigger pulse in the three phase is needless.
