Adaptation circuit for a fuel cell system of a vehicle, drive system and method for operating a drive or the drive system

摘要

The invention has for its object to provide a matching circuit for a fuel cell system, a drive system for a vehicle and a method for operating a drive system for a vehicle, which enables an economical operation of the fuel cell system. This object is achieved by an adaptation circuit (8) for a fuel cell system (2) of a vehicle (1) having an input interface (9) for connecting an output voltage (US) of a fuel cell arrangement (6) of the fuel cell system (2) to a drive output interface (13 ) for supplying a power train (3) for a drive motor (5) with a drive voltage (UA) and with a supply output interface (10) for supplying a supply bus (11) for peripheral components (12) with a supply voltage (UV), wherein the matching circuit ( 8) can be switched to a special operating state, in which the supply voltage (UV) is greater in magnitude than the drive voltage (UA) is formed.
