摘要
Unless overmodulation is adopted, utilization of DC bus of the Modified Space Vector Modulation (MSVM) is a drawback that has severely limited the applicability of this modulation technique. This paper presents some solutions that, looking for a good compromise between increasing the use of DC bus and reducing common mode currents, allow to apply MSVM to most electrical drives on the market. Furthermore, the choice of the switching patterns is performed according to the sign of the load currents thus reducing the common mode voltage variations to a single pulse per switching period in presence of large dead-times. Experimental results are presented in order to confirm the feasibility of the proposed approach.
