초록
In this paper, a novel six-level inverter is proposed. Voltage regulation is applied at DC-link and flying capacitors through the implementation of phase-shifted carrier-based modulation with zero-sequence voltage injection. The performance of the proposed structure has been verified under various modulation indices, where low voltage ripple is achieved at each capacitor and total harmonic distortions (THD) of line voltage at unity modulation index is about 15.95%.
