Thermal Characterisation of a Double-D Pad

Inductive power transfer (IPT) systems have been researched as one of the methods for wireless electric vehicle charging. One aspect often overlooked in IPT systems is the rise of temperature in the pads during operation in applications where active cooling is difficult, such as in a buried structure within a roadway. This paper conducts a thermal analysis of a buried double-D (DD) primary pad in simulations and experimentally validates the findings.
