In this article, a modulating waveform generation for carrier-based space vector pulse width modulation (PWM) control for a split-phase induction motor drive is proposed for the first time. The modulating waveform synthesis for the carrier-based dodecagonal space vector PWM (DSV-PWM) is based only on the sampled reference phase amplitude. The present approach for the DSV-PWM generation is based on vector time computation and accessing the output vectors from the look-up table. This article synthesizes a modulating waveform compared to a triangular carrier waveform to generate the DSV-PWM for the two-level conventional split-phase induction motor inverters. Such as conventional hexagonal space vector modulating waveform, here, dodecagonal space vector modulating waveform is generated by adding the zero sequence signals of third, fifth, and seventh order harmonics to the fundamental or modulating signal. A simple approach, like in a hexagonal space vector scheme, is proposed with less mathematical computation, such that it can be easily implemented in the digital platform. The proposed scheme is explained and verified with experimental results. |
