Losses minimization control for an integrated multi-drives topology devoted to hybrid electric vehicles [IECON 2017 - 43RD ANNUAL CONFERENCE OF THE IEEE INDUSTRIAL ELECTRONICS SOCIETY, 2017]

This paper deals with the study and implementation of a losses minimization control method for an integrated multi-drives topology used to interface a multi windings induction machine to more storage units in hybrid electric vehicle parallel drivetrains. The main target is to optimize the management of multi-directional power flows, by reducing the power losses in the induction machine as well as in each energy storage units. The proposed control strategy continuously searches for the best compromise among the torque demand, the power capability of each storage unit and the overall power losses. In such a way, a significant improvement in the overall efficiency is obtained. Simulations and experimental tests confirm the effectiveness of the proposed method.
