An Integrated SRM Powertrain Topology for Plug-In Hybrid Electric Vehicles With Multiple Driving and Onboard Charging Capabilities

Plug-in hybrid electric vehicles (PHEVs) possess the merits of low carbon emissions, high fuel efficiency, and long driving mileage, and thus attract more and more attention. This article presents an integrated switched reluctance motor (SRM) powertrain topology for PHEVs, which owns multiple driving and battery-charging functions with less power electronic devices than traditional topology. In motor driving mode, four driving modes are achieved according to the road conditions. Motoring and braking operations can be successfully implemented. For battery-charging mode, three charging modes are implemented without extra battery chargers. A three-channel interleaved boost converter with power factor correction (PFC) capability is constituted by utilizing the SRM windings and integrated converter circuit to charge the traction battery from the grid. An integrated half-bridge isolation dc/dc converter is employed to charge the auxiliary battery from the generator or traction battery. A proof-of-concept prototype platform is built and experiments are carried out on a three-phase 12/8 poles SRM to verify the effectiveness of the proposed integrated drive topology and the corresponding control schemes.
