Sensitivity Analysis of Inductive Power Transfer Systems for Electric Vehicles Battery Charging

This paper investigates the sensitivity of inductive power transfer systems for electric vehicles battery charging. The goal of the analysis is to assess the impact of harmonics on the transferred power and on the efficiency, in order to define the main specifications for design and calibration of relevant measurement systems. The first harmonic approximation models of a Series/Series system and a Series-Parallel/Series system is developed to perform the analysis with respect to the variations of main operating parameters and coils mutual coupling. The resulting model predictions are validated by comparison with PSIM simulations.
