Abstract

The space vector modulation algorithm (SVM), which is based on the gh coordinates is very simple in vector choosing and time calculation. It can avoid a large number of trigonometric function computing. It is applied to three-level or more than three-level SVPWM digital control algorithm. Finally, the algorithm is realized respectively based on Matlab simulation environment and DSP. The simulation and test results have verified the effectiveness of the algorithm.
