Wireless power transmission system using multiple coils

A wireless power transmission system using multiple coils, comprising:

• 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, and
• wherein 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, and
• wherein:
• the secondary coil and the capacitors are connected with each other in series if the equivalent resistance of the load is less than a predetermined first threshold value,
• the secondary coil and the capacitors are connected with each other in parallel if the equivalent resistance of the load exceeds a predetermined second threshold value,
• the second threshold value being greater than the first threshold value, and
• the capacitors are comprised of two capacitors and respectively connected with the secondary coil in series and in parallel if the equivalent resistance of the load is the predetermined first threshold value or more and the predetermined second threshold value or less.
