摘　　要：本系统采用MCS-51系列单片机8052为基础来实现对三相全控桥的触发控制.讨论了α角和单片机定时器时间常数间的关系,同时提供了一种简单有效的触发脉冲的程序设计方案,由软件控制可产生不同顺序的6组触发脉冲.本设计可广泛应用于电力电子控制系统中.This system realizes the triggering control of three-phase bridge rectifier based on 80C52,one of single chip microcomputers of MCS-51 series.Discusses the relation between the control cape α and the time constant in single chip microcomputer's timer.At the same time,provides a simple and valid program-designing method for the trigger pulses,and controlled by software,it can generate 6 group of trip-pulses in different order.This design can be extensively applied in power and electronics control systems.
