Abstract
In this paper, we describe how the quality factor of a coil depends on the frequency in the case of litz wires for wireless, inductive power applications. The importance of this work relates to the observation that the link efficiency of a induced coupled system depends critically on the quality factors of the transmitter and receiver coils. An important design choice in these systems is the frequency at which the application operates. The winding of the litz wire and the presence of ferrite shifts the frequency at which the maximal quality factor, and thus link efficiency, is obtained.
