Abstract

The present invention provides efficient measures to improve electrical performance in a mobile side output circuitry of a wireless power transmission system. A mobile side circuitry of the wireless power transmission system has a mobile side transformer stage (30) comprising at least one primary side winding (36_1, ..., 36_n, 36) and a plurality of secondary side windings (38_1, ..., 38_n). To the plurality of secondary side windings (38_1, ..., 38_n) there are connected a plurality of mobile side AC / DC converters (40_1, ..., 40_n). According to a first alternative of the present invention output terminal pairs (42_1, ..., 42_n) of the plurality of mobile side AC / DC converters (40_1, ..., 40_n) are connected in series. According to a second alternative of the present invention output terminal pairs (42_1, ..., 42_n) of the plurality of mobile side AC / DC converters (40_1, ..., 40_n) are connected in parallel. According to a third alternative of the present invention mobile side AC / DC converters (40_1, ..., 40_n) are grouped into a plurality of mobile side output groups (48_1, ..., 48_g) such that output terminal pairs within each mobile side output group (48_1, ..., 48_g) are connected in series and output terminal pairs of different mobile side output groups (48_1, ..., 48_g) are connected in parallel.

Description

technical field [0001] The present invention relates to wireless power transfer systems, and more particularly to the arrangement of modular output structures at the mobile side of the wireless power transfer system, the measurement of the output current of the modular output structures, and the synchronization for operation at the mobile side of the wireless power transfer system The control method of the rectifier. Background technique [0002] In general, wireless power transfer systems have many advantages over conductive power transfer systems. For electric vehicles, for example, this means plugging in cables is no longer necessary. [0003] figure 1 A schematic diagram of a wireless power transfer system 100 known in the art is shown. [0004] Such as figure 1 As shown, the wireless power transfer system 100 includes on the fixed side a DC / AC converter 102 , a fixed side controller 104 , a fixed side compensation capacitor 106 , and a transmitter coil 108 connected...
