摘要
介绍了利用硬件描述语言VHDL设计的一种基于CPLD的PWM控制电路 ,该PWM控制电路具有PWM开关频率可调 ,同侧2路信号互锁、延时时间可调、接口简单等特点 。
It is introduced that a PWMcontrol circuit based on CPLD is designed by using the VHDL.The conˉtrol circuit has such features that the PWMfrequency is adjustable,the two out-signals of the same side are locked each other and have logic delay,interface is simple etc.It can be applied to DC servo system.
