基于DSP的空间电压矢量脉宽调制变频调速系统

A Frequency Conversion Timing System of SVPWM Based on DSP

本文叙述了一种基于DSP的恒压频比控制,空间电压脉冲宽度调制(SVPWM)的异步电动机变频调速系统。重点介绍了恒压频比控制的原理和利用TMS320LF240实现SVPWM的方法,并最终给出了实验结果。

This paper introduces a frequency conversion timing system of asynchronous motor with SVPWM technique and constant V/F principle based on DSP. It＇s a stress to explain the principle of constant V/F and the implementation of SVPWM by using TMS320LF2407. The experiment result is favored.
