【摘要】 本系统采用MCS-51系列8031单片机为基础结合外围器来实现对可控硅变流器的触发控制。为实现触发脉冲与电源信号的同步,采用锁相环技术及过零触发的方法。由软件控制可产生不同变流器(单相桥、三相半波、三相全控桥等)所要求的不同触发脉冲。更多还原

【Abstract】 The system discussed in this paper is to control the triggering of silicon controlled rectifier,based on chip microprocessor 8031 of series MCS51,together with some exterior devices.To synchronize the triggering pulse and power signal,phase locked loop and surpassing zero triggering are adopted.Various triggering pulses to fit various rectifiers can be obtained through the control of software.更多还原
