Abstract

This paper presents a new switching strategy controlling a new three-level voltage source inverter, resulting in different 25 space voltage-vectors. The new inverter combines some desirable features of two and three-level inverters. The proposed open-leg switching strategy intentionally opens one of the three inverter-legs per-time, in a pre-planned sequence. Thus, the number of allowed states becomes 64 compared to 27 originally proposed by other modulation strategies. For a wye-connected load operating at low modulation index (Mth conduction mode is presented, eliminating the low frequency harmonics in the neutral-point current, consequently reducing the dc-link capacitors sizes, and cost. Analytical models, computer simulation results, and experimental verification are presented.
