This paper presents a novel 150°conduction mode of widely used three phase voltage source inverter (VSI). In 150° conduction mode of three phases VSI each switch conducts for 150° time period. So the output phase voltage of VSI becomes 7 level, 12 step waveform compared to only 4 level and 3 level in 180°and 120° conduction modes respectively. This result into 50% harmonic reduction compared to conventional 180° and 120°conduction mode .Presence of THD using FFT analysis is mentioned in this
