Abstract：Technique of single-phase multilevel space vector modulation is proposed through introducing the space vector modulation into single-phase multilevel converter in this paper. The space vector diagram of single-phase multilevel converter is presented according its common structure, and the principle of single-phase multilevel space vector modulation is deduced. Taking example for hybrid cascade seven-level inverter, simulation and experiment of two different modulation algorithms is performed based on single-phase multilevel space vector modulation. Simulation and experimental results indicate that the single-phase multilevel space vector modulation technique can flexibly apply the redundancy of switch state to achieve the modulation algorithm satisfied with demand by abstracting simple voltage space vector from complex switch state combination, which is of many advantages as simple algorithm, easy implement and strong generality.
