| 摘要 |
The invention relates to a method (42) for operating a wireless power transmission arrangement (10) having a primary element (18) and a secondary element (20), which are inductively couplable, in order to transmit electric power from the primary element (18) to the secondary element (20), wherein an adjustable load impedance is coupled to the secondary element (20), wherein electrical substitute variables are ascertained for an electrical model (34) of the power transmission arrangement (10), wherein the electrical model (34) takes account of an electrically conductive object (32) in a transmission link (28) between the primary element (18) and the secondary element (20), wherein an impedance value for the load impedance is determined on the basis of the electrical substitute variables and an ascertained electrical power loss from the object (32) arranged in the transmission link (28), and wherein the load impedance is adjusted to the impedance value. |
