A PWM strategy for six-phase dual stator induction motor fed by two identical voltage source inverters

A new SVPWM method used to control a six-phase dual stator induction motor is presented in this paper. By using decomposition technique, 12 vectors which have maximum magnitude are used to form a 12-side polygon and 12 sectors. The voltage reference vector is synthesized by two vectors with maximum magnitude, in which one vector is the sector's side and the other is the adjacent sector's side. This method corresponds to synthesizing the reference vector in individual three-phase VSIs. Simulation results, obtained from an 18-kW prototype machine, are presented.
