摘要
介绍了一类适用于风机、水泵负载节能运行的数字式 SPWM交流变频调速系统 .该调速装置采用IGBT作为主功率器件 ,1 6位单片机 80 C1 96KC为控制核心 ,SLE4 52 0生成 SPWM波 ,调速系统频率值采用数字设定 .文中阐述了系统的设计原理 。
In this paper,a digital control of variable frequency drive system based on high carrier frequency SPWM converter is discussed. The device fits to fan or pump load. It uses IGBT as main switch, 80C196KC as the control unit, SLE4520 as SPWM waveform generator. The control algorithm is discussed and results are given.
