This paper presents a study on the behaviour of the currents in a 1-D resonator array of inductive power transfer (IPT) systems that can be used for electric vehicle (EV) charging. The resonator array is used to ease misalignment issues between the receiver and the transmitter and to improve the transmission distance. Besides, IPT systems with resonator arrays may offer the possibility of dynamic charging. The analysis is performed assuming a generic position of the receiver over a 1-D array. A theoretical model - tolerant to the misalignment of the receiver - has been developed and experimentally verified. The model is used to determine the currents in the system. The obtained results highlight significant stresses on the circuit components that must be considered in the design stage of the apparatus, especially when a large power is transferred, such as in the case of EV charging.

Abstract

This paper presents a study on the behaviour of the currents in a 1-D resonator array of inductive power transfer (IPT) systems that can be used for electric vehicle (EV) charging. The resonator array is used to ease misalignment issues between the receiver and the transmitter and to improve the transmission distance. Besides, IPT systems with resonator arrays may offer the possibility of dynamic charging. The analysis is performed assuming a generic position of the receiver over a 1-D array. A theoretical model - tolerant to the misalignment of the receiver - has been developed and experimentally verified. The model is used to determine the currents in the system. The obtained results highlight significant stresses on the circuit components that must be considered in the design stage of the apparatus, especially when a large power is transferred, such as in the case of EV charging.
