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.

This paper presents several RF-to-DC converter topologies and compares their performances based on measurements made on fabricated prototypes. A medium range wireless low power transmission experiment is presented. A low power DC-DC boost converter designed rectenna-generated energy conditioning is also discussed.
