Abstract
This paper presents a new switching strategy controling 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 (OLSS) 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 de-link capacitors sizes, and cost. Analytical models, computer simulation results, and experimental verification are presented.
