摘要：介绍了一种自行研制的基于硬件描述语言（VHDL）和复杂可编程逻辑器件（CPLD）的PWM发生器的设计，在产生正反两路PWM波形信号的同时，实现了两路信号互锁、延时时间可调。该发生器采用数字化设计，结构简单、控制精确、可在线编程。

Abstract: The design of PWM generator based on VHDL and CPLD was introduced. The two positive and negative phase PWM wave outsignals were produced, the two outsignals locked each other and logic delay were realized. The generator is designed with the digital, it has simple structure, accurate control and can be programming on line.
