Wireless power receiver for controlling wireless power by using switch
First Claim
1. A wireless power receiver for wirelessly receiving power from a wireless power supplier, the wireless power receiver comprising:
- a power reception unit configured to wirelessly receive the power from the wireless power supplier;
a rectifier configured to rectify the received power into DC power;
a power adjustor configured to disconnect the power reception unit from the rectifier for a first period and to connect the power reception unit to the rectifier for transferring the received power to the rectifier for a second period to adjust a size of the received power to be transferred to the rectifier; and
a controller configured to;
determine whether to increase or decrease the size of the received power to be transferred to the rectifier, andin response to the size of the received power being transferred to the rectifier being determined to be increased, increase a duration of the second period,wherein the power adjustor is electrically connected to the power reception unit and the rectifier,wherein the size of the received power to be transferred to the rectifier is adjusted according to a ratio of a duration of the first period to the duration of the second period, andwherein the received power is not transferred from the power reception unit to the rectifier during the first period.

15. A control method by a wireless power receiver for wirelessly receiving a supply of power from a wireless power supplier, the method comprising:
-
receiving power wirelessly from the wireless power supplier; determining whether to increase or decrease a size of the received power to be transferred to a rectifier of the wireless power receiver; in response to the size of the received power being transferred to the rectifier being determined to be increased, increasing a duration of the second period; controlling such that the power is not output for the first period by configuring a closed loop within the wireless power receiver, and the power is output to the rectifier for the second period, wherein a size of the power to be transferred to the rectifier is adjusted according to a ratio of a duration of the first period to the duration of the second period. - View Dependent Claims (16, 17, 18, 19, 20, 21)
