This article presents new multilevel modulation strategy based on single carrier-based pulse-width modulation for dual six-phase (twelve-phase) symmetrical/asymmetrical star-end winding converter. The four standard voltage source inverters with one bidirectional switch (MOSFET/IGBT) per phase constitute the power circuit. Further, through the two capacitor bi-directional switch link the neutral link. An algorithm-based single carrier zero-shifted five-level modulation (SCZSFM) modulates each two-level VSI as a five-level output multilevel inverter. The complete AC drive is numerically modelled in MATLAB/PLECS software and tested for predicting theoretical background.
