Abstract
A power reception device includes a first capacitor and a second capacitor, and first capacitor and second capacitor are arranged to be adjacent to each other on a same side when viewed from a power reception coil, such that a second external electrode faces a fourth external electrode, and first capacitor and second capacitor are arranged such that a distance between second external electrode and fourth external electrode is shorter than a distance between a first external electrode and a third external electrode.
Claims8
A power reception device that receives electric power from a power transmission device in a contactless manner, with said power reception device facing said power transmission device,
- said power reception device comprising:
- a power reception coil;
- a first capacitor connected to one end of said power reception coil;
- and
- a second capacitor connected to the other end of said power reception coil, wherein
- said first capacitor includes a first external electrode and a second external electrode, and said one end of said power reception coil is connected to said first external electrode,
- said second capacitor includes a third external electrode and a fourth external electrode, and said other end of said power reception coil is connected to said third external electrode, and
- said first capacitor and said second capacitor are arranged to be adjacent to each other on a same side when viewed from said power reception coil, such that said second external electrode faces said fourth external electrode, and said first capacitor and said second capacitor are arranged such that a distance between said second external electrode and said fourth external electrode is shorter than a distance between said first external electrode and said third external electrode.
A power transmission device that transmits electric power to a power reception device in a contactless manner, with said power transmission device facing said power reception device,
- said power transmission device comprising:
- a power transmission coil;
- a first capacitor connected to one end of said power transmission coil;
- and
- a second capacitor connected to the other end of said power transmission coil, wherein
- said first capacitor includes a first external electrode and a second external electrode, and said one end of said power transmission coil is connected to said first external electrode,
- said second capacitor includes a third external electrode and a fourth external electrode, and said other end of said power transmission coil is connected to said third external electrode, and
- said first capacitor and said second capacitor are arranged to be adjacent to each other on a same side when viewed from said power transmission coil, such that said second external electrode faces said fourth external electrode, and said first capacitor and said second capacitor are arranged such that a distance between said second external electrode and said fourth external electrode is shorter than a distance between said first external electrode and said third external electrode.
