Abstract A novel difference value space vector pulse-width modulation (SVPWM) algorithm is proposed in the paper based on the conventional SVPWM analysis. In the proposed method, the SVPWM is implemented through the 3 phase voltage difference computation, and judged voltage vector space's sector through the sequence of phase voltages, without coordinate transformations, trigonometric function, inverse trigonometric and vector decomposition to the sector in the conventional SVPWM method. The validity of proposed method is verified by the simulated and experimental results. It shows that the simplicity of the code program and reduction of CPU execution time while using in a real time control system.

Key words： SVPWM voltages' difference value difference value SVPWM pulse width's difference value
