基于80C52的三相可控整流电路触发脉冲的实现

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.-Based on 80C52 three-phase controlled rectifier circuit trigger pulse to the system using the MCS- 51 series 8052 based on the three-phase full-controlled bridge trigger control. Discuss the relationship between the alpha angle and microcontroller timer time constant, The program design also provide a simple and effective trigger pulse can be controlled by software to produce the type of the order of 6 trigger pulse, this design can be widely used in power electronic control system.
