Document Type and Number:
WIPO Patent Application WO/2017/164598
Kind Code:
A1
Abstract:
A wireless power transmission system using multiple coils comprises a transmitter; and a receiver, wherein the transmitter includes a module for receiving a predetermined voltage, and a primary coil for generating a primary resonance frequency in accordance with the received voltage. The receiver spaced apart from the transmitter includes a load for emitting light, capacitors connected in series or in parallel in accordance with an equivalent resistance of the load, and a secondary coil for generating a secondary resonance frequency greater than the primary resonance frequency.
