摘　　要：脉冲电化学光整加工技术是近年来新发展的一种高效的光整加工方法 ,需要用高频窄脉宽大功率的脉冲电源。该电源的设计采用了单片机AT89s5 2作为主控部分 ,通过 82 5 4 2可编程定时器 /计数器输出频率和占空比可调的脉冲方波 ,并使用M 5 796 2AL来驱动和保护IGBT ,实现了把直流电压信号斩波成脉冲电压信号输出。Pulse electrochemical finishing technique has been developed as a new finishing method with high efficiency in recently years. The technique requires high frequency and narrow pulses current. This paper presents the principle of the source. The single chip AT89s52 is used as the main controller, and the regulation of frequency and duty ratio of pulse wave is attained by the programmable timer/counter 8254-2. M57962AL is applied to drive and protect IGBT .By so, direct current is chopped into pulse current.
