Abstract
The invention concerns a wireless power transfer arrangement () including a primary side () and a secondary side () where the primary side includes an input stage () for converting an input power to an AC primary output and a primary resonator () for receiving the AC primary output and inducing a magnetic field () for wireless power transfer through an air gap (). The secondary side () includes a secondary resonator () for converting the power received through the magnetic field () to an AC secondary output and an output stage () for converting the AC secondary output to a DC secondary output. A controller () is adapted to control independently of each other a frequency of the AC primary output to be at a resonance frequency of the resonators and the power transferred from the primary side () to the secondary side () by controlling the voltage or the current of the AC primary output. By locking the frequency of the system to the resonance frequency enables any easy power control simply by controlling the current or the voltage of the primary resonator ().
