Abstract

The invention relates to a non-contact supply apparatus and a non-contact supply system. The non-contact supply apparatus comprises: a supply apparatus including a supply-purposed primary coil for supplying electricity to a supply-purpose secondary coil in a non-contact way and a drive circuit for driving the supply-purposed primary coil; and a relay apparatus including a magnetic body acting as a magnetic circuit. And the non-contact supply apparatus is configured such that: the supply-purposed primary coil, the magnetic body and the supply-purposed second coil are in an orderly arrangement aligning with the direction of the magnetic flow in a magnetic field generated in the central parts thereof, non-contact supply being conducted to the supply-purposed secondary coil from the supply-purposed primary coil via the magnetic body.

Description

technical field [0001] The invention relates to a non-contact power supply device and a non-contact power supply system. [0002] This application is based on Japanese Patent Application No. 2014-36265 filed in Japan on February 27, 2014, Japanese Patent Application No. 2014-38534 filed in Japan on February 28, 2014, and Japanese Patent Application No. 2014-38534 filed in Japan on March 3, 2014. Priority of Japanese Patent Application No. 2014-40216, the contents of which are incorporated herein. Background technique [0003] In recent years, vehicles driven by electricity are used. [0004] Therefore, it is necessary to supply power to the vehicle. [0005] For example, the power supply equipment is used to supply power to a parked vehicle. [0006] The power supply device is capable of supplying power to the vehicle in a non-contact manner. [0007] For example, it has been studied to have a secondary coil for non-contact power feeding on the bottom of the vehicle, and...
