SYSTEM FOR INDUCTIVELY TRANSFERRING POWER FROM A PRIMARY DEVICE TO A SECONDARY DEVICE, PRIMARY DEVICE, AND METHOD FOR OPERATING SUCH A SYSTEM

Abstract

An inductive power transfer system is provided, comprising a primary device, a secondary device, and a control unit, wherein the primary device is arranged and designed to inductively transfer power via a primary oscillating circuit to a secondary oscillating circuit of the secondary device during the transfer of power, wherein the control unit is designed to record secondary power data of the secondary device and to determine primary target power data using a power characteristic and the recorded secondary power data, wherein the power characteristic comprises reference primary power data as a function of reference secondary power data, wherein the control unit is designed to record primary power data of the primary device and to detect a foreign object using a comparison of the primary target power data with the primary power data.
