Title:
MAGNETIC RESONANCE POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/125926
Kind Code:
A1
Abstract:
The present invention relates to a magnetic resonance power transmission device using the magnetic sympathetic vibration (or resonance) of evanescent waves generated around a wireless power transmission coil, and more particularly relates to a magnetic resonance power transmission device whereby power transmission can take place wirelessly when an electricity-receiving-unit sympathetic-vibration coil is sympathetically vibrated at the same frequency as an electricity-transmitting-unit sympathetic-vibration coil, by ensuring that there is evanescent wave coupling wherein an electromagnetic wave moves through a short-distance magnetic field from the electricity-sending unit to the electricity-receiving unit between a sending sympathetic-vibration coil and a receiving sympathetic-vibration coil. The magnetic resonance power transmission device of the present invention comprises: a power-source supplying unit which supplies a power source for transmitting power wirelessly by means of magnetic resonance; a wireless power sending unit for inputting the power source supplied from the power-source supplying unit, and sending power by means of magnetic resonance; a magnetic resonance signal generating unit for effecting control in such a way that magnetic resonance is generated in the wireless power sending unit; a wireless power receiving unit for receiving the power transmitted from the wireless power sending unit; and a load that operates by means of the power received from the wireless power receiving unit, and, in the wireless power sending unit and wireless power receiving unit, the respective coils and capacitors are connected in parallel and power is sent and received wirelessly.
