A control circuit (400) is used in a wireless power receiver (300) that receives power signals from a wireless power transmitter. A power detection unit (402) detects reception power (PRX) received by the wireless power receiver (300). A control unit (404) generates control signals (CE) for controlling the transmission power (PTX) to be transmitted by the wireless power transmitter. An error determination unit (406) determines that an error has occurred if the reception power (PRX) detected by the power detection unit (402) has reduced, even if the control signals (CE) do not indicate a reduction in transmission power (PTX). |
