Abstract

This paper presents the integration of an inductive position sensor and a contactless energy transfer system. Integration is obtained by separation of both functions in the frequency domain and is realized by means of a network with multiple resonance frequencies, such that both systems operate across one pair of coils. The magnetic properties are verified with FEM simulations and performance analyses are conducted for both functions. The position sensor has an error of 7.3 μm and there is no crosstalk between the contactless energy transfer system and the position sensor.
