摘要
本文采用了单片机PIC16F877和SPWM(Slne Pulse WidthModulation)的技术。提出了一种基于PIC16F877产生的智能控制信号用软件程序去控制SPWM的新方法,设计了一种高效、低成本、功能齐备的小型变频器。
This paper introduces the technique of single chip PIC16F877 and SPWM(Sine Pulse Width Modulation),raises a new method based on PIC16F877 bring intellective control signal to control SPWM ,and designs high-efficiency, low cost and full function small frequency converters.
