Abstract

This contribution propose a design procedure applicable to many kinds of wireless or contactless energy transfer systems. The design procedure is limited to near field wireless energy transfer systems in resonant operation. Therefore it is well applicable to systems with a primary side power oscillator or systems with a control strategy that forces an equal system behavior compared to a primary side power oscillator. In resonant operation the input impedance and voltage transfer function of different natural frequencies describe the system behavior and will be calculated analytically in this contribution. Not only the knowledge of these transfer functions but also the knowledge of basic magnetic properties lead to a readily applicable design procedure.
