NON-CONTACT POWER RECEPTION DEVICE, VEHICLE HAVING THE SAME, NON-CONTACT TRANSMISSION DEVICE, AND NON-CONTACT POWER TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power transmission system using a resonance technique, capable of bi-directionally transmitting electric power.

SOLUTION: A resonance coil 210 of a vehicle 200 contactlessly receives AC power output from a resonance coil 150 of a transmission apparatus 100 by implementing resonance through the resonance coil 150 and an electromagnetic field. An inverter 240 receives the AC power received by the resonance coil 210 from an electromagnetic induction coil 230 and converts the AC power into DC power for output to a power line. To output electric power from the resonance coil 210 to the resonance coil 150 of the transmission apparatus 100, the inverter 240 converts the DC power received from the power line into AC power and outputs the AC power to the electromagnetic induction coil 230, and through the electromagnetic induction coil 230, the power is supplied to the resonance coil 210.
