Abstract
Efficient measures to improve electrical performance in a mobile side output circuitry of a wireless power transmission system are provided. The mobile side circuitry of the wireless power transmission system has a mobile side transformer stage comprising at least one primary side winding and a plurality of secondary side windings. To the plurality of secondary side windings there are connected a plurality of mobile side AC/DC converters. According to a first alternative of the present invention output terminal pairs of the plurality of mobile side AC/DC converters are connected in series. According to a second alternative of the present invention output terminal pairs of the plurality of mobile side AC/DC converters are connected in parallel. According to a third alternative of the present invention mobile side AC/DC converters are grouped into a plurality of mobile side output groups such that output terminal pairs within each mobile side output group are connected in series and output terminal pairs of different mobile side output groups are connected in parallel.
