摘要
三相变频器的控制核心是由单片机产生的三相SPWM驱动信号。本文探讨使用单片机编写三相SPWM驱动程序的方法,并使用Proteus仿真软件运行所编写的程序,直接观察到由程序所产生的SPWM波形。
Frequency converter is widely used in three-phase AC motor＇ s rotation control. The key step of developing frequency converter is to generate SPWM wave. This paper probes into the method of programming three-phase SPWM driver by using single-chip microcomputer. It also discusses the programming procedures by using the operating situation of Proteus simulation software and the SPWM wave generated throught direct observation.
