Title:
POWER-RECEIVING DEVICE, NONCONTACT POWER-FEEDING SYSTEM, AND NONCONTACT POWER-FEEDING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/248766
Kind Code:
A1
Abstract:
In the present invention, AC power received by a power-receiving coil (31) which receives power from the outside without contact using magnetic field coupling is rectified by a first power supply unit (41) and converted to direct current, and is supplied as the main power used by a load device (45). A second power supply unit (42) is connected to the front stage of this first power supply unit, and outputs power used for controlling the first power supply unit as direct current. By doing this, it is possible to ensure a stable power supply for control in the circuit configuration when the load device receives power.
