Abstract:

This paper presents a clear methodology for achieving the optimum design of LCL bidirectional inductive wireless power transfer system (BIWPTS) for electric vehicle (EV) applications. The proposed strategy depends on electromagnetic field computations joined with analytical models. A three dimensional finite element model (3D-FEM) for 8 kW polarized double-D (DD) power pad was modeled, optimized and built. Moreover, the choice of the power factor correction and impedance matching elements was investigated. Following the proposed design considerations, a BIWPTS model was developed in MatLab Simulink and its outcomes were compared with the theoretical model results. Additionally, a small scale prototype was assembled using the same design with reduced dc voltage levels. The models were tested during charging and discharging operation and good correlation were seen between every one of them.
