    摘要:This paper proposes a common-mode voltage (CMV) suppression strategy for synchronized space vector modulation (SSVM) in the overmodulation region for high dc voltage utilization requirements. In two divided overmodulation region, reference voltage vectors of SSVM are synthesized in the light of superposition principle for easy implementation. Moreover, zero vectors are replaced by two opposing active vectors to reduce CMV. In the proposed method, the amplitude of CMV could be reduced to one-third for the inverter with diode front end. The performance of the proposed strategy is verified by simulations and experiments.
