WIRELESS POWER TRANSFER DEVICE

摘要

PURPOSE: A wireless power transmitting device is provided to reduce resonant frequency by multiplying capacitance between laminated repeater coils. CONSTITUTION: A base substrate(110) comprises a base coil. Relay substrates(120-140) comprises transmission coils and are arranged to be separated from the base substrate. The relay substrates comprise a first relay substrate, a second relay substrate, and a third relay substrate. The second relay substrate is arranged between the first relay substrate and the third substrate. A contact plug passes through the base substrate and relay substrates. The contact plug interlinks one ends of the transmission coils. The contact plug comprises a first contact plug and a second contact plug. The transmission coils has many rev count than the base coil. The transmission coils transmits and receives an electric source signal with a magnetism resonance method.
