摘　　要：介绍了一种变频变压（ＶＶＶＦ）、脉宽调制（ＰＷＭ）的交流（ＡＣ）电动机转达调节控制系统，该系统采用ＭＣＳ－８０９８单片机作为控制部件。文中给出了产生正弦脉宽调制（ＳＰＷＭ）序列的算法，及该控制系统的工作原理、硬件和软件框图。This paper introduces a PWM(pulse-width modulation )control system of VVVF(variable-voltage & variable-frequency )using a MCS-8098 single-chip microcomputer,which is used for therotative velocity regulation of the AC motors. The algorithm of the generating SPWM(sinusoided pulse-width modulation ) sequence,the principle of the system operation,the hardware and software blockdiagrams of the control system are given in the poper.
