Title:
CONTACTLESS POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/001959
Kind Code:
A1
Abstract:
The disclosed contactless power transmission device performs power transmission from a power transmission unit (100) to a power receiving unit (200) via a resonance magnetic field. The device is provided with a power transmission unit (100) which resonates at a resonance frequency (f0), at least one relay unit (300) which is capable of resonating at a frequency selected from multiple frequencies including said resonance frequency (f0), and a resonance control unit (600) which outputs information specifying the resonance conditions of the relay units (300) depending on the arrangement of the power receiving unit (200), and causes the relay units (300) to resonate at resonance conditions specified by said information.
