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