Asymmetrical Six-Phase Space Vector Pwm Scheme
Mokslas: Lietuvos Ateitis, 2014 Multiphase electric motors have smaller torque pulsations and are more reliable that their three-phase alternatives. However, standard electricity grids around the world are three-phase, so power inverter is needed to drive multiphase motors. Inverter is
