Diode-clamped, three-level, three-phase inverters display mid-point voltage excursions that cause low-frequency harmonic distortion in the output voltage spectrum. This paper illustrates that a significant reduction in the excursion is achieved by adopting a multi-phase approach. Practical and simulation results are presented.
