Title:
WIRELESS POWER RECEIVER AND CONTROL METHOD FOR WIRELESS POWER RECEIVER
Document Type and Number:
WIPO Patent Application WO/2021/096327
Kind Code:
A1
Abstract:
According to various embodiments, a wireless power receiver for receiving wireless power from a wireless power transmitter, comprises: a resonant circuit configured to generate alternating-current power on the basis of a magnetic field generated by the wireless power transmitter; a power conversion circuit configured to convert the alternating-current power generated by the resonant circuit into direct-current power; and a control circuit, wherein the power conversion circuit comprises a first diode, a second diode, a third diode, a fourth diode, and a first switch, and the control circuit can be configured to adjust at least one of a voltage or a current of the direct-current power output from the power conversion circuit, by checking the at least one of the voltage or the current of the direct-current power output from the power conversion circuit and adjusting a phase of a first control signal to be applied to the first switch. Various other embodiments are possible.
