WIRELESS ELECTRIC POWER TRANSMISSION SYSTEM BASED ON MULTIPLE POWER TRANSMITTER

摘要

PURPOSE: A wireless electric power transmission system based on a multiple electric power transmitter is provided to reduce the change of electric power transmission efficiency by arranging a receiving coil among multiple transmitting coils. CONSTITUTION: A wireless electric power receiver comprises a receiving coil(22). Multiple wireless electric power transmitters comprise a transmitting coil. The number of the multiple wireless electric power transmitters is two. Mutual inductance between the receiving coil and the first transmitting coil(24-1) decreases. Mutual inductance between the receiving coil and the second transmitting coil(24-2) increases.
