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...

This paper presents a new modification for the most-common, simple, and well-known three-phase six-switch voltage source inverter (VSI). In this modification, each one of the six transistors conducts for 150deg instead of the known 180deg or 120deg conduction modes. For a wye-connected load, the output phase-voltage becomes a seven-level, 12 steps waveform. This results in a 50% reduction of the total...

This paper presents a new modification for the most-common, simple, and well-known three-phase voltage source inverter (VSI). In this modification, each one of the six transistors conducts for 150deg instead of the usual 180deg or 120" conduction modes. For a wye-connected load, the output phase-voltage becomes a seven-level, 12 Steps waveform-which is closer to the sinusoidal waveform-than the...
