Design considerations for a contactless battery charger
Contactless power transfer using inductive coupling is a well-known way to transfer energy from a transmitter to a receiver without any physical link. The applications are multiple. In this paper, the design and control of such a system for a contactless battery charger is investigated. The behaviour of the battery turns the system into a non-linear one. A solution dealing with the compensation topologies which aims to simplify the control of the transformer without any additional power electronics is proposed.
