POWER SUPPLY SYSTEM
First Claim
1. A power supply system comprising:
- a power supply unit including a power supply side coil to which electric power is supplied; and
a power reception unit including a power reception side coil arranged to electromagnetically resonate with the power supply side coil and receive the electric power from the power supply side coil,wherein impedances of the power supply unit and the power reception unit are matched at a position where a center axis of the power supply side coil is displaced with respect to a center axis of the power reception side coil.

Abstract
Provided is a power supply system which can reduce a decrease in transmission efficiency caused by displacement of a power supply side coil with respect to a power reception side coil and which can supply power from a power supply unit to a power reception unit with high efficiency. A power supply part includes a power supply side helical coil (33) to which power is supplied. A power reception part includes a power reception side helical coil (51) which electromagnetically-resonates with the power supply side helical coil (33) and receives power from the power supply side helical coil (33). Impedances of the power supply part and the power reception part are matched at position where center axes (Z1, Z2) of the power supply side helical coil (33) and the power reception side helical coil (51) are displaced with respect to each other.
