Abstract: A novel Dispersion SVPWM Algorithm is proposed in the paper based on the conventional SVPWM analysis,especially in two parts which are sector distinguish and dwelling time.Novel algorithm is based on the angle of voltage vector which get through estimating algorithm,avoiding 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.
