Claim 0:
1. A converter system for transferring power, comprising:
a first DC-DC module,
a second DC-DC module, and
a first control unit,
the first DC-DC module being connected to a first high voltage interface of a high voltage system and to a first low voltage interface of a low voltage system, the first DC-DC module comprising a first AC-DC unit, a first DC-AC unit and a third AC-DC unit,
the second DC-DC module being connected to a second high voltage interface of the high voltage system and to a second low voltage interface of the low voltage system, the second DC-DC module comprising a second AC-DC unit, a second DC-AC unit and a fourth AC-DC unit,
the first high voltage interface and the second high voltage interface being independent of each other,
each DC-AC unit being connected to each high voltage interface, and each AC-DC unit being connected to each low voltage interface, the third and fourth AC-DC units being connected to an AC interface via a power factor correction (PFC) unit and configured to supply power to the high voltage system and/or to supply power to the low voltage system, and
the first control unit being connected to the first DC-DC module and configured to supply power via the second DC-DC module in case of a failure in the first DC-DC module.
