PSIM based dynamic simulator for analysis of SPHEV operation

This paper describes a PSIM simulator for the analytical approach of the HEV (Hybrid Electric Vehicle) power train operation. For this research, a series-parallel type HEV (SPHEV) are chosen to apply the Forward-Facing approach simulation method. As the traction power of the series-parallel type HEV can be supplied from both of the ICE (Internal Combustion Engine) and the traction motor, the planetary gear is used for the mechanical connection among ICE, generator, and motor. For the ICE, a gasoline fuel type engine is selected and modeled with DC motor. IPMSM (Interior Permanent Magnet Synchronous Motor) and 3.7V 40Ah Lithium Polymer battery are chosen as a traction motor and ESS (Energy Storage System). DC/DC converter is used for the electrical connection between battery and DC-Link. After all components of the SPHEV power train have been designed and modeled separately, all components of SPHEV are assembled and controlled by the primary controller which is programed according to the desired driving strategy of HEV. Finally, some remarkable PSIM simulation results are discussed.
