Claim:
1. A capacitor arrangement for an input circuit or intermediate circuit of a single voltage converter, comprising: the single voltage converter comprising an inverter circuit configured to receive a DC voltage at an input thereof and convert the DC voltage to an AC voltage at an output thereof; at least two capacitors and two connection nodes at the input of the inverter circuit, and switching members configured to selectively alter an arrangement of the at least two capacitors with the two connection nodes, wherein the at least two capacitors are connected to the connection nodes in parallel with each other in a first operating state of the switching members and connected to the connection nodes in series with each other in a second operating state of the switching members, wherein the switching members are arranged such that an inflow of charge into the at least two capacitors is prevented in a third operating state in which the at least two capacitors are decoupled from the inverter circuit.
