Abstract: An arrangement comprising at least one electrical voltage source (1) and one first voltage converter circuit (2) with an output (3) and an input (4). In this arrangement, the electrical voltage source (1) is connected to the input (4) of the first voltage converter circuit (2) and the output (3) of the first voltage converter circuit (2) can be connected to an electrical load (5). An input circuit (6) comprising an electromechanical switching element (7) and an inductance (8) is formed and the switching element (7) automatically opens and closes once or several times in dependence on a physical quantity, wherein an output circuit (10) comprising a capacitive element is formed.
