Abstract
A power reception device includes a plurality of power-receiving coils, a plurality of rectifier elements, and a convergent output smoothing capacitor. The plurality of power-receiving coils are positioned in place relative to the housing in such a manner that the plurality of power-receiving coils each include first conductor portions extending along a side surface of the housing. The plurality of rectifier elements are connected respectively to the plurality of power-receiving coils. The convergent output smoothing capacitor stores electric energy output from the plurality of rectifier elements.
Claims17
A power reception device for a wireless power supply system, comprising:
- a columnar body having a space defined therein;
- a plurality of power-receiving coils arranged along an exterior of the columnar body;
- a plurality of resonance capacitors connected respectively to at least two of the plurality of power-receiving coils to configure a plurality of resonant circuits;
- a plurality of discrete rectifier elements electrically connected respectively to the at least two of the plurality of power-receiving coils;
- a plurality of smoothing capacitors, each connected to a respective one of the discrete rectifier elements;
- and
- a convergent output smoothing capacitor electrically connected to the plurality of discrete rectifier elements, wherein
- electric energy output from the plurality of discrete rectifier elements converges in the convergent output smoothing capacitor for storage and supply of power,
- the columnar body is wrapped with the plurality of power-receiving coils that are arranged in a manner so as not to coincide with each other along a perimeter defined by at least one side surface of the columnar body, and
- the plurality of discrete rectifier elements are disposed within the columnar body.
