摘要：
A wireless power feeding unit includes a power transmitting module and a power receiving module. The power transmitting module includes a first inverter circuit which is connected to a power source via a switch, a first transmission coil connected to the first inverter circuit, a second inverter circuit which is connected to the power source or another power source not via the switch, a second transmission coil which is connected to the second inverter circuit, and a power transmission control circuit which controls the first and second inverter circuits. The power receiving module includes a first reception coil opposed to the first transmission coil and a second reception coil opposed to the second transmission coil. During operation of the first and second inverter circuits, even while supply of power to the first inverter circuit is stopped, the power transmission control circuit maintains control of the second inverter circuit.
