RESONANCE-TYPE POWER TRANSMISSION DEVICE AND RESONANCE-TYPE POWER TRANSFER SYSTEM

摘要

The present invention is provided with: an inverter circuit (7) which is provided with a resonance circuit provided with an inductor and a capacitor, and which outputs power; and a transmission antenna (2) for transferring power outputted by the inverter circuit. The inverter circuit changes the inductance of the inductor and/or the capacitance of the capacitor in accordance with the input impedance of the transmission antenna.
