An Integrated Electrified Powertrain Topology With SRG and SRM for Plug-In Hybrid Electrical Vehicle

With the advantages of less carbon dioxide emissions and high fuel efficiency, plug-in hybrid electrical vehicle (PHEV) is an attractive means of transportation. This article presents an electrified powertrain for PHEV containing switched reluctance generator (SRG), switched reluctance motor (SRM), and integrated power converters, which could achieve various driving and flexible on-board charging functions. The operation states of SRG and SRM with the integrated topology is analyzed. Five driving modes for PHEV are implemented and can be smoothly switched by controlling the front-end converter according to the load conditions. For the PHEV charging mode, a single-phase ac–dc rectifier is constituted by the windings and power converter of SRG with the capability of input power factor correction. The traction and auxiliary batteries chargers are formed by the windings and power converter of SRM. Three charging modes also are achieved and no complex control strategies are required to avoid the rotation of rotors. The three-phase 12/8 poles SRG and SRM experimental platform are built. The experiments are carried out to verify the effectiveness of proposed integrated powertrain and the corresponding control schemes.
