Abstract

There are provided a magnetic coupling unit and a magnetic coupling system which are capable of reducing energy loss when operations using magnetic coupling between magnetic devices are performed. The magnetic coupling unit includes: one or more magnetic devices each capable of being magnetically coupled with other magnetic device in other unit; and one or more coupling reinforcing sections each reinforcing the magnetic coupling.

Description

technical field [0001] The invention relates to a magnetic coupling unit having magnetic means such as coils, and a magnetic coupling system comprising a plurality of such magnetic coupling units. Background technique [0002] In recent years, power feeding systems (non-contact power feeding systems, wireless charging systems) that perform non-contact power supply (power transmission) for CE devices (Consumer Electronics) such as mobile phones and mobile music players have attracted attention . Therefore, charging can be started by placing the electronic unit (secondary side unit) on the charging tray (primary side unit) without inserting (connecting) a connector of a power source such as an AC adapter into a unit. In other words, terminal connections between the electronic unit and the charging tray are unnecessary. [0003] As a method of performing non-contact power supply in this way, an electromagnetic induction method (for example, Japanese Unexamined Patent Applicat...
