Implementation of a three-level SVPWM algorithm in gh coordination based on DSP

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.
