Integrated Isolated OBC for EVs with 6-phase Traction Motor Drives

This work deals with a new topology of on-board integrated battery charger intended for road electric vehicles equipped with a 6-phase traction motor drive. The proposed OBC topology deeply integrates the battery charger within the e-drive powertrain, thus reducing cost and volume of the charger respect to non-integrated solutions. Moreover, galvanic insulation is provided, differently from all fully integrated charger in the literature. Finally, the charger has embedded PFC capability, so the AC grid current is absorbed at unitary power factor and low THD. Extensive simulation results show the feasibility of the proposed solution.
