Charger for contactless chargeable battery powered device, e.g. mobile telephone, has second conductor arrangement that produces screening field at least partly compensating alternating field of first conductor arrangement

摘要

The charger (1) has a housing (2) bounding an accommodation space accessible via an opening and a conductor arrangement in the space that produces an alternating electromagnetic field in a charging region of the space. A second conductor arrangement between the first conductor arrangement and the opening produces a screening field that at least partly compensates the alternating field of the first conductor arrangement.
