...Although ML-VSIs were originally developed to reach higher voltage operation, before being restricted by semiconductor limits, the extra switches and sources (provided by multiple dc-link capacitors) could be used to generate different output-voltage levels, enabling the generation of a stepped waveform with less harmonic distortion, reducing dv/dt’s and common-mode voltages, and enabling operation under fault conditions and converter modularity [21]....
