摘　　要：在常规的高压脉冲调制电源系统设计中,信号生成部分采用分离原件电路搭建而成,存在可重复性差、信号同步性差、电路复杂、精度低等问题,本文提出了一套基于单片机与CPLD为主体的脉冲信号设计。实验结果表明,通过此方法,可以有效的提高系统的重复性,实现自动控制等功能,并且简化了相应电路。In normal power system of high-voltage pulse modulation, the generated signal is separated by the original circuit structures, but the poor repeatability, weak signal synchronization, complexity circuit and low accuracy need to be improved. In this paper, the pulse signal design based on the MCU and CPLD was presented. The results indicate that the new methods can not only increase the repeatability, but also achieve the automatic control with corresponding simplified circuit.
