Beschreibung
Zusammenfassung:	The invention relates to a receiver unit (200), which is configured to cooperate with a transmitter unit (100) separate from the receiver unit for the wireless transfer of energy, said transmitter unit (100) comprising a primary coil (L1), which can be supplied with a supply voltage (UV), wherein the receiver unit (200) comprises a secondary coil (L2), to which a first intermediate circuit capacitor (CZ,1) is connected via a rectifier (210), and a power unit (240), to which a consumer (225) and/or an energy store (220) are connected, wherein the receiver unit (200) comprises a second intermediate circuit capacitor (CZ,2), to which the power unit (240) is connected, wherein the first intermediate circuit capacitor (CZ,1) and the second intermediate circuit capacitor (CZ,2) are connected to one another in a separable manner via a switch (S7), and wherein the receiver unit (200) comprises an auxiliary supply unit (250), which is connected to the rectifier (210) for the purpose of voltage supply and which is configured to close the switch (S) to connect the first intermediate circuit capacitor (CZ,1) to the second intermediate circuit capacitor (CZ,2) when an output voltage (Uout,H) of the auxiliary supply unit (250) exceeds a specified threshold value.
