Abstract
This paper presents a new modification for the mostcommon, simple, and well-known three-phase six-switch voltage source inverter (VSI). In this modification, each one of the six transistors conducts for 150° instead of the known 180° or 120° conduction modes. For a wye-connected load, the output phasevoltage becomes a seven-level, 12 steps waveform. This results in a 50% reduction of the total harmonic distortion (THD), 75% reduction of voltage distortion factor (DF), and the lowest harmonic order (LOH) becomes 11 rather than 5. Comprehensive study for the three conduction modes is proposed, and a comparisons with other types of voltage source inverters, like the neutral point clamped (NPC) and the multilevel inverters (MLI) were also carried out. Simulation and experimental results show the contribution of the proposed strategy.
