摘要： A converter system for transferring power, a vehicle including such a converter system and a method for transferring power in such a converter system. The converter system includes a first DC-DC module, a second DC-DC module and a first control unit. The first DC-DC module is 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 second DC-DC module is 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 first high voltage interface and the second interface are independent of each other. The first control unit is 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.

摘要： A power supply comprises a DC power source, first and second DC/DC converters, and a protection circuit. The DC power source provides DC power at a variable bulk voltage. The first DC/DC converter converts the DC power from the DC power source to DC power at a high voltage suitable for powering a high-voltage load. The second DC/DC converter receives DC power from the first DC/DC converter, converts the received DC power to DC power at a low voltage, and delivers the DC power at the low voltage to a low-voltage load. The protection circuit selectively transfers DC power from the first DC/DC converter to the high-voltage load. The DC power source may be an AC/DC converter receiving AC power from a power generator driven by an aircraft engine.

The micro grid further includes first and second remote distribution nodes, and first and second splice enclosures, each splice enclosure having a power input port, a data input port, a power tap port, a data tap port, a power output port and a data output port. A first composite power-data cable is coupled between the first power port and the first data port of the first power sourcing equipment device and the power input port and the data input port of the first splice enclosure. A second composite power-data cable is coupled between the second power port and the second data port of the first power sourcing equipment device and the power input port and the data input port of the second splice enclosure. The power tap port and the data tap port of the first splice enclosure are coupled to a power input port and a data input port of the first remote distribution node, respectively.
