Abstract :
In this paper, unified voltage modulation technique for dual three-phase induction machine (DTPIM) is described. The dual three-phase induction machine is composed of two symmetric three-phase winding sets, which are spatially phase-shifted by 30 electrical degrees. The machine is driven by a six-phase Inverter, which is divided into two independent three-phase inverters with a common dc link voltage. Using the concept named "effective time", various carrier-based PWM scheme can be easily implemented to the machine and generalized to multiphase machines with arbitrary three-phase winding sets. The feed-forward (v/f control) scheme is addressed. The validity of the proposed technique is verified by the simulating results.
