Document Type and Number:
WIPO Patent Application WO/2016/135893
Kind Code:
A1
Abstract:
[Problem]
To reduce radiated emissions generated during wireless power transmission.
[Solution]
A control device serving as an embodiment of the present invention controls a wireless power transmission device equipped with a power transmission unit and a power reception unit, said control device being equipped with a first control unit. The power transmission unit includes a first power transmission coil unit and a second power transmission coil unit. The power reception unit includes a first power reception coil unit, a second power reception coil unit, a first rectifier, a first DC-DC transformer, a second rectifier, and a second DC-DC transformer. The control unit controls the voltage conversion ratio of the first DC-DC transformer and/or the voltage conversion ratio of the second DC-DC transformer on the basis of a first detection value pertaining to the current amplitude of the first power transmission coil unit and a second detection value pertaining to the current amplitude of the second power transmission coil unit.
