基于TMS320F2812及IPM的异步电动机变频调速系统硬件设计

Hardware Design of Variable Frequency Variable Speed System of Induction Motor Based on TMS320F2812 and IPM

介绍了采用TMS320F2812作为系统控制的核心部件,辅助以智能功率模块IPM和其它外部器件,设计出的一种通用异步电动机变频调速系统。讨论了系统的硬件设计,给出了硬件的设计方案。系统软件采用C语言编写,实现了SPWM正弦脉宽调制波形。实验结果表明,该系统具有一定的实际应用价值,可用于多种工业控制场合。

Making use of TMS320F2812 as kernel units, intelligent power module IPM and other exterior components as auxiliary units, a kind of universal variable frequency variable speed system of an induction motor （IM） was designed. The system hardware design was discussed and its design project was shown. The system software was programmed by C language, and SPWM waveform was achieved. The experimental results indicated that the system had not only applied value, but also used in many industrial control occasions.
