Classification: CPC H  B  Y | IPC B  H

Claim 12:
13. A method for transferring power in a converter system, comprising the following steps:
connecting a first DC-DC module 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,
connecting a second DC-DC module 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,
connecting each DC-AC unit to each high voltage interface, and each AC-DC unit to each low voltage interface,
connecting the third and fourth AC-DC units to an AC interface via a power factor correction (PFC) unit, the third and fourth AC-DC units being configured to supply power to the high voltage system and/or to supply power to the low voltage system, and supply power from the high voltage system to the AC interface,
connecting a first control unit to the first DC-DC module, and
supplying power via the second DC-DC module in case of a failure in the first DC-DC module,
the first high voltage interface and the second high voltage interface being independent of each other.
