Abstract
An energy supply assembly includes a supply input that provides a first voltage VIN with a maximum output current; a first voltage converter connected to the supply input to convert the first voltage VIN into a second voltage; an intermediate storage element connected to the first voltage converter to temporarily store electric energy of the second voltage; at least one first supply output connected to the supply input to provide the first voltage VOUT1; at least one second supply output connected to the intermediate storage element to provide a further supply voltage VOUT2; a measuring device to measure a current received via the supply input and/or a current output via the first supply output; and a control circuit that actuates the first voltage converter, wherein the control circuit is configured to actuate the first voltage converter on the basis of the measured current such that the current output via the at least one first supply output and the current received by the first voltage converter together do not exceed the maximum output current.
