Abstract
In a wireless power transfer arrangement () power is wirelessly transferred from a primary side () to a secondary side () across an airgap () by means of a primary resonator () that generates a magnetic field () and a secondary resonator () that receives the power by picking up the magnetic field (). The secondary side () includes an output stage () that receives the AC power provided by the secondary resonator () and generates a DC output () to be provided to a load. A current sensing arrangement () senses the AC current flowing from the secondary resonator () to the output stage () and provides a current sense signal () to a power transfer controller () that controls the power transfer of the wireless power transfer arrangement () based on the current sense signal (). And the current sense signal () is provided to a switching controller () that controls the switching of a synchronous rectifier of the output stage () that converts the AC power () provided by the secondary resonator () to the DC output ().
