Claim 13:
14. A method for operating a converter with a primary side and a secondary side galvanically isolated therefrom, comprising:
provision of a secondary-side functional unit which is operated in dependence on auxiliary information generated on the primary side,
a primary-side voltage supply device which provides a supply voltage, and
a power transmission device, which has a switching unit for switching the supply voltage and a transmission unit, which transmits the switched supply voltage to the secondary side, in order to convert the supply voltage into an operating voltage for the functional unit,

primary-side provision of a clock signal for the switching unit, a frequency of which is changed on the primary side as a function of the auxiliary information, the primary-side provision varying the frequency of the clock signal within a frequency interval in which a voltage translation ratio with respect to input and output voltages of the power transmission device is substantially frequency invariant;
secondary-side generation of at least one use signal representing the auxiliary information from a secondary voltage provided by the transmission unit; and
secondary side providing a use signal to the functional unit.
