Wireless power receiver and method for controlling the same

A wireless power receiver (210) that receives wireless power from a wireless power transmitter and a control method thereof are provided, wherein the wireless power receiver receives (S501) the wireless power from the wireless power transmitter; rectifies (220) the wireless power (S503); determines (S505) whether a ripple of a voltage value of the wireless power is greater than or equal to a preset threshold; and if the ripple of the voltage value of the wireless power is greater than or equal to the preset threshold, changes (S507)at least one element value of the wireless power receiver to suppress the ripple below the preset threshold.
