Abstract
A voltage converter arrangement for the electrical coupling of a fuel cell unit is provided, which is connected or can be connected on the input side, to a traction network, which is connected or can be connected on the output side, and which comprises a high-voltage battery may comprise a measuring unit for measuring the input voltage supplied by the fuel cell unit, and a comparison unit, which is electrically connected to the measuring unit and is in turn electrically coupled to a controller unit, which is designed to cause the fuel cell unit to be operated at predeterminable operating points, and which is configured to seek time-varying operating points from the fuel cell unit in an impedance operation. A fuel cell system and a method for operating a voltage converter arrangement is also provided.
