Wireless power receiver

摘要

A wireless power receiver is provided for wirelessly receiving driving power from a wireless power transmitter. The wireless power receiver includes a power reception unit for wirelessly receiving the driving power from the wireless power transmitter. The wireless power receiver also includes a rectifier for rectifying the driving power from the power reception unit into a Direct Current (DC) power type. The wireless power receiver additionally includes a load unit for storing the rectified driving power from the rectifier. The wireless power receiver further includes a controller for detecting an amount of the rectified driving power stored in the load unit to control output from the rectifier to the load unit. The wireless power receiver also includes an impedance adjuster for adjusting an impedance in the power reception unit according to the amount of the rectified driving power stored in the load unit.
