SVPWM Technology of Switch Mode Determined by Hardware Based on DSP

文章详细介绍了SVPWM技术的基本原理,并给出了一种基于TMS320F2407A DSP的由硬件决定开关切换模式的SVPWM控制方法及其软件设计。实验结果表明,由硬件决定开关模式在感应电动机控制系统中可以大大降低微处理器的软件工作量,降低功率开关器件的频率,减少开关损耗。

The paper introduced fundamental principle of SVPWM technology, and gave a SVPWM control method of switching mode of switch determined by hardware based on TMS320F2407A DSP and its software design. Experimental result showed that switch mode determined by hardware could reduce work load of software of microprocessor in induction motor control system, reduce frequency of power switch, and cut down wastage of switch.
