Apparatus for generating and distributing electrical power to loads in a vehicle

摘要

An apparatus for generating and distributing electrical power in a vehicle which has at least one electric drive motor connected via a converter to a fuel cell unit, with the fuel cell unit being connected to at least one first, one second and one third voltage network, and with each voltage network having at least one associated electrical load and/or at least one associated energy store. The first voltage network is formed by the fuel cell voltage network and is connected via a first bidirectional DC/DC converter to the second voltage network and the first bidirectional DC/DC converter provides DC isolation between the first voltage network and the second voltage network. The second voltage network is connected via a second bidirectional converter to the third voltage network.
