Abstract

This paper proposes a new, high performance space vector PWM technique that takes advantage of (i) the ability to control the dc link voltage through front-end PWM rectifiers in motor drives and (ii) a class of recently introduced switching sequences that involve division of the active state duration in a subcycle. The modulation index is always kept at the maximum value, and the dc link voltage is varied to control the magnitude of ac line voltages. The new class of sequences is most suitable at high modulation indices. Hence, the proposed PWM results in significant savings compared to conventional SVPWM with or without dc link voltage control. The THD performances of the various techniques are analyzed using the concept of stator flux ripple. Experimental results validate the superior performance of the proposed technique.
