A Novel Naturally Sampled Space Vector Pulse Width Modulation Algorithm

Abstract

A novel algorithm for the naturally sampled SVPWM in overmodulation region is proposed in this paper, the comparison between naturally sampled SVPWM and conventional SVPWM in overmodulation region is carried out. It was proved that naturally sampled SVPWM could be used not only in under modulation but also in overmodulation region by the results of analysis and simulation. The work was done by this paper shows a promising use of the naturally sampled SVPWM. The obviously advantage is that it could be implemented by using DSP with only simplified computation and short time of on line calculation, or just by using analog circuits without the help of microprocessor at all. All the work did by this paper provide a platform for the implementation of naturally sampled SVPWM operating in under modulation and over modulation region.
