A novel Dispersion SVPWM Algorithm is proposed in the paper based on the conventional SVPWM analysis. In per control period, the dwelling time of basic voltage vector can be calculated by the 3 phase voltage dispersion, and without coordinate transformations, trigonometric function, inverse trigonometric function and vector decomposition, which simplified the conventional SVPWM algorithm. The proposed method is effective by the simulated and experimental results. It shows the simplicity of the code program and reduction of CPU execution time in a real time control system.
