异步电动机变频调速技术及其计算机实现

VVVF and It's Implementation Based on Single-chip Microcomputer

详细论证了一种新型通用变频装置的控制原理及实现方案，以最新流行的空间电压矢量PWM调制法为基础，主控电路采用80C196KC单片机，有效地简化了系统的结构和使用。最后，探讨了变频调速技术的发展及其在印刷业应用的前景。

The controlling and producing strategy of a novel general VVVF System was discussed. The cantrolling method is based on newly current Space voltage Vector PWM (SVPWM)strategy. The PWM pattern generation and the system control are archieved by software of the 16 bit single-chip microcomputer 80C196KC, so the system construction is highly simplified. At last the development of VVVF system and its application in printing were discussed.
