Document Type and Number:
WIPO Patent Application WO/2013/111430
Kind Code:
A1
Abstract:
In this non-contact power supply system, inductance can be easily adjusted. Power is supplied in a non-contact manner to a pickup coil of a carriage from a power supply line that is provided along a traveling path. A variable inductor, which is provided with a magnetic body constituting a magnetic circuit, a main coil wound on the magnetic body, and a control coil wound on the magnetic body, is provided, and inductance of the main coil is controlled by controlling a control current to be applied to the control coil of the variable inductor.
