可逆饱和计数器的设计与应用

Design and application of reversible and saturable counter

针对基于电子计数器的可逆步进控制系统不允许出现计数器状态跃变问题,对单时钟和双时钟可逆计数器,提出了4种以集成可逆计数器为核心的可逆饱和计数器设计方案.通过增加状态译码器,用计数使能控制法和时钟脉冲控制法实现饱和计数.可逆饱和计数器在数控直流电源中的应用说明,该设计方案有效可行.

In view of the problem that the state step of the counter is often not hopeful or allowed,in the reversible step control system based on electronic counter,four kinds of reversible and saturable counter based on integrated reversible counter and their design methods are proposedSaturable counting can be realized by using the counting enable control method and the clock pulse control method through adding outside state decoder to the common counter.An application example of the counter in the digitally controlled direct power shows that this design is feasible
