RESONANCE-TYPE POWER TRANSMISSION DEVICE

WIPO Patent Application WO/2017/187610

A1

The present invention comprises: an inverter circuit (102) that outputs a high-frequency power; an inverter circuit (103) that outputs, at the same frequency as a harmonic included in said high-frequency power, a high-frequency power; a power control unit (1041) that controls the magnitude of the output power of the inverter circuit (103); a transmission antenna (105) that resonates at the same frequency as the high-frequency power output by the inverter circuit (102) and has a transmission coil (1051), said transmission coil (1051) being connected to an output end of the inverter circuit (102); and a suppression antenna (106) that resonates at the same frequency as the high-frequency power output by the inverter circuit (103) and has a suppression coil (1061), said suppression coil (1061) being connected to an output end of the inverter circuit (103) and positioned at the outer circumference or inner circumference of the transmission coil (1051). The direction of a current that flows through the transmission coil (1051) and the direction of a current that flows through the suppression coil (1061) are opposite directions.
