摘要
采用单片机8031,定时器/计数器8254,HEF4752等器件设计了SPWM变频调速系统,并对系统的工作原理,系统能达到的功能及其设计的方法进行了讨论。
In this paper we have designed a SPWM variable-frequency velocity modulation system by using chip computer 8031, timer/counter8254, HEF4752, and so on. The principles of SPWM inverter. The functions and the design methods of this system are also discussed thoroughly.
