Title:
受電装置
Document Type and Number:
Japanese Patent JP6925919
Kind Code:
B2
Abstract:
To provide a power-receiving device which can adequately retain an input impedance of a rectification circuit at an optimum value.SOLUTION: A power-receiving coil 11 receives AC power transmitted from a transmission coil 2c for sending AC power in a non-contact manner. A bridge rectification circuit 20 rectifies the AC power received by the power-receiving coil 11 into a DC power, and supplies the DC power to a load part 3. An adjustment capacitor group 40 is connected in parallel with the bridge rectification circuit 20, and charges a DC power supplied from the bridge rectification circuit 20 to the load part 3. A switch part 50 switches the connection of the adjustment capacitor group 40 and the bridge rectification circuit 20 to ON or OFF. A detector part 70 serves to detect a voltage and a current of the DC power supplied to the load part 3. A control part 80 controls the switch part 50 based on the voltage and current detected by the detector part 70, and adjusts an amount of charging power to be charged into the adjustment capacitor group 40.SELECTED DRAWING: Figure 1
