Abstract :
Based on six divided regions of space vectors, the potential position of the reference voltage vectors is firstly determined according to the principle of rotating vector normalization method. Then the effective time of three synthesized vectors is calculated by the principle of the volt-second balance principle. Last the working orders starting with the positive small vectors is proposed. Simulation results are included for verifying the validity of the proposed SVPWM method.
