Abstract
A charging device for charging a battery pack, having a control circuit for a switched-mode power supply transformer assigned to the charging device, the transformer having at least one primary winding switchable using a power switch and at least one first secondary winding for generating an electrical output voltage for charging the battery pack, the output voltage having a first amplitude which is predefinable by a control unit and adjustable using a first voltage limiting control loop. The transformer has at least one second secondary winding for generating at least one electrical auxiliary voltage having a second amplitude which is predefinable by the control unit and adjustable using a second voltage limiting control loop in order to at least reduce an energy feed assigned to an operation of the control circuit from the primary winding to the secondary windings in a standby mode of the control circuit.
