摘要
当今脉宽调制技术在电火花微细加工所使用的脉冲电源中得到广泛应用。本文就硬件实现两类数字脉宽调制器的工作原理进行比较。作者经过实践证实了第二类脉宽调制器的可行性和优点。
Now pulsewidth modulating technology is widely used in pulse power needed by electric spark fine machining.This paper compares the working principles of realizing two types of digital pulsewidth modulators with hardware. Thepracticability and merit of the second trpe pulsewidth modulator are proved by practical application.
