This paper introduces an increased utilization of the dc-link voltage of a five-leg voltage source inverter (VSI) based on the rotor flux angle control technique for dual induction motors, IM. The main purpose is to utilize additional abilities provided by a multi-motor drive system in limited operating conditions. Generally, a multi-motor drive system is widely used in electric vehicles (EVs), traction systems and in several industrial applications. A dual IM drive system is investigated in this paper, where field-oriented control (FOC) scheme and space vector pulse-width modulation (SVPWM) technique are used for the drives control. Therein, additional rotor angle control is implemented to increase the maximum modulation index. The proposed control technique allows the control of two independent three-phase IM. Under limited conditions, both motors can achieve high modulation index values and decreased losses as well. Simulation studies and results carried out in PLECS software package show the effectiveness and feasibility of the proposed control strategy. Experimental results presented proved the idea of the proposed solution.
