Voltage harmonics integral factors estimation of multilevel inverter with space vector modulation of two delta voltages

The paper describes some details of the voltage source multilevel inverter space vector PWM algorithm developed on the base of one of the more general algorithms for oblique-angled coordinates of two delta voltages. The instantaneous output voltage waveform simulation has been carried out, and voltage THD and harmonics integral factors dependences on the amplitude modulation index are presented.
