A multi-source inverter (MSI) topology features significant advantages over conventional MSI converters such as NPC-based and T-Type-based topologies, including a lower number of switching devices, higher efficiency, and better thermal distribution of switching devices. A space vector modulation (SVM) scheme for MSI topologies presented herein and for conventional MSI topologies uses three or four adjacent vectors to generate a reference voltage vector, resulting in lower voltage and current total harmonic distortion (THD) at the MSI output, a lower switching frequency, and increased efficiency relative to conventional MSI modulation. Embodiments are suitable for use in electric vehicles and energy storage systems.
