Scaling Rules at Constant Frequency for Resonant Inductive Power Transfer Systems for Electric Vehicles

The paper proposes the development of a set of rules for the resizing of inductive power transfer systems with particular attention to the ones dedicated to the charge of electric vehicles. These rules aim at the construction of down-scaled prototypes allowing the study and the design with benefits in terms of costs, time consumption and flexibility. The theoretical results are experimentally validated by comparing a 1.1 kW system with its down-scaled version.
