A novel voltage modulation technique of the space vector PWM

In this paper, a novel voltage modulation scheme is described. With the effective voltage concept, the actual switching times for each inverter legs are deduced directly as a simple form. With the help of the presented zero sequence voltage allocation algorithm, the proposed PWM method has the high performance voltage generation capability exactly same as the conventional three phase symmetry space vector PWM method. As well as giving a detailed explanation vector PWM and PWM algorithm, the paper presents the comparison results with the conventional method such as space vector PWM and sinusoidal PWM method.
