Abstract

A wireless power transfer system comprises a power transmitter () arranged to generate a wireless inductive power transfer signal for powering a power receiver (). The system comprises a temperature controlled power loop setting an operating temperature for a heating part of a powered device. The system further comprises a receiver () for receiving a first temperature for a part of a powered device where the powered device is powered by the power receiver (). A comparator () compares the measured temperature to a first reference temperature associated with the power transmitter (). In response to the first temperature exceeding the reference temperature, a controller () proceeds to restrict the power of the power transfer signal and/or to generate a user alert. The first temperature may specifically relate to a contact surface of the powered device and the reference temperature may be a maximum allowable temperature of a contact surface for receiving the powered device during power transfer.
