WIRELESS POWER TRANSMISSION SYSTEM

摘要

In a power transmitter device, a power transmitter side active electrode and a power transmitter side passive electrode are formed. In a power receiver device, a power receiver side active electrode and a power receiver side passive electrode are formed. The power transmitter side active electrode is rectangle that is shorter in a first direction and longer in a second direction. The power receiver side active electrode is rectangle that is longer in the first direction and shorter in the second direction. The power transmitter side active electrode and the power receiver side active electrode are formed so as that lengths of overlapping area in the first and second directions do not change in a placement receivable area on the power transmitter device, within which the power receiver device is allowed to be displaced.

1. A wireless power transmission system comprising:
a power transmitter device including:
a planar outer surface having a power transmitter receiving region with a first cross-sectional area,an AC generator circuit,a power transmitter side active electrode coupled to the AC generator circuit, anda power transmitter side passive electrode coupled to the AC generator circuit; and a power receiver device including:
a housing having a second cross-sectional area less than the first cross-sectional area of the power transmitter device,a load circuit,a power receiver side passive electrode coupled to the load circuit, anda power receiver side active electrode coupled to the load circuit, wherein, when the power receiver device is positioned on the planar outer surface within the power transmitter receiving region, the power transmitter side active electrode overlaps the power receiver side active electrode at an overlapping region that has a constant area independent of the position of the power receiver device in the power receiving region.
