Abstract

This paper reports thermal analysis of a 35kW wireless power transfer (WPT) pickup module to keep the system´s efficiency at different temperatures. Temperature effects are first considered by looking at change in efficiency of the system which is influenced by change in resistance and capacitance at different temperatures. Then, we introduce methods to improve the overall performance of a high powered WPT system by utilizing appropriate wires and capacitors, and cooling the device by means of an optimized heat sink.
