Simple space vector PWM scheme with quarter-wave symmetric output voltage waveform for three-phase multilevel inverter

The paper describes the simple technique for the quarter-wave symmetric output voltage waveform formation of the three-phase multilevel inverter. This technique is based on the applying the appropriate natural nonsymmetric three-segment vectors switching sequence to the recently proposed simple voltage source multilevel inverter space vector PWM algorithm. Some Mathcad simulated voltages waveforms and loci are shown, and the delta voltage total harmonic distortion (THD) and first three orders n-order integral voltage harmonics factors are presented as the functions of the amplitude modulation index.
