Scale Reduction for Modeling and Prototyping of Inductive Power Transfer System for EV Applications

In this article, the scale reduction method is applied to an induction power transfer system for electric vehicle (EV) charging for its rapid and low-cost prototyping. In addition, a co-simulation method is proposed, which is based on the coupling between a circuit analysis and a finite-element (FE) analysis. Then, it is proposed to combine the scale reduction method with the co-simulation method to consider, at the same time, the nonlinearities due to the power electronic converter and the magnetic material characteristics of the system. Finally, a 1 kW experimental IPT system is proposed to validate both methods.
