文中综述了交流电机变频调速所需正弦脉宽调制信号用计算机软件生成的原理 ,进而介绍了
This paper introduces principle application of generating forming by computer the digital PWM signal used for VVVF equipment in the speed concrol system of AC motor. Then the construction of generator forming the mutual-complement PWM single in each of three phase in single chip microcomputer 8XC196MC and the method generating SPWM waveform with equivalent-area approach for 8XC196MC are discussed.
