Abstract

The roadway powered electric vehicle (RPEV) system is a unique electric vehicle system that receives electric power by inductive coupling from an inductor buried beneath the road surface. The analytical model of the system that transfers power from the wayside to the vehicle battery and DC traction motor is analyzed. This model includes the roadway inductor, the vehicle-mounted pick up inductor, and the onboard circuitry for control/conditioning of the coupled power. The equivalent circuit model of the inductive power coupling system is derived. Based on this model, the electrical characteristics of the system are explained. Trade-offs in selecting system parameters are discussed. All test results have tended to confirm simulation results obtained using the analytical model
