Title:
POWER FEEDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/062758
Kind Code:
A1
Abstract:
This power feeding device for transmitting power in a non-contact manner has: a DC power supply; an inverter circuit 32 connected to the DC power supply; a resonant circuit 33 that is connected to the inverter circuit and includes a transmission coil 35; sensors 61-64 that detect the values of currents flowing through the circuits or the values of voltages applied to the circuits; and a control device connected to the inverter circuit and the sensors. When allowing the power feeding device to transmit power in a non-contact manner, the control device controls the inverter circuit so as to convert the DC voltage supplied from the DC power supply to an AC voltage and supply the AC voltage to the resonant circuit. When diagnosing an abnormality of the sensors, the control device controls the inverter circuit so as to supply the DC voltage supplied from the DC power supply to the resonant circuit without converting to the AC voltage and diagnoses the abnormality of the sensors on the basis of the detection values of the sensors at this time.
