Abstract
An energy transfer system for wireless energy transfer includes a transmitter unit having a primary coil supplied with a supply voltage and a receiver unit separate from the transmitter unit having a secondary coil to which a DC link capacitor is connected by a rectifier. The energy transfer system further includes a first device configured to determine a value of a DC link voltage applied on the DC link capacitor when the supply voltage is applied on the primary coil, and a second device configured to perform at least one function based on the determined value of the DC link voltage or a variable derived therefrom. A receiver unit is configured to interact for wireless energy transfer with a transmitter unit separate from the receiver unit.
