Abstract

This paper presents practical details involved in the design and implementation of a contactless battery charger that employs a pair of neighboring printed circuit board (PCB) windings as a contactless energy transfer device. In this paper, a prototype contactless battery charger developed for the application to cellular phones is used as an example to address design considerations for the PCB windings and energy transfer circuit and demonstrate the performance of the contactless charger adapted to a practical application system.
