摘要
本文介绍我们近期取得的异步电动机PWM变频调速的一些研究成果。由于采用了大功率晶体管和单片机,并注重开发了软件功能,所以,系统结构简单,可靠性提高。可方便地改变控制规律与适用于不同类型负载的控制模式。系统通过了实验。
This paper introduces our recent research achievements in PWM vari- able-frequency speed adjusting system of an asynchronous motor.Because of adopting GTR and single slice microcomputer and exploiting software function,the system has simple structure and high reliability,and can easily change the control pattern and control model suiting different loads.The experiment with the system has been successful.
