Abstract
A DC converter is connected to a DC source on its input side. On the output side, the DC delivers a converted DC voltage to at least one electric consumer via a cable connection. To improve such a DC converter in that it has a comparatively simple structural design and is able to reliably convert high DC voltages even in the case of high power, and in such a way that the reliability of the converter is increased and cooling systems entailing high costs can be dispensed with, the DC converter comprises a plurality of DC converter components, each of said DC components being, on the input side, serially connected to the DC source and, on the output side connected in parallel to the cable connection so as to provide the converted DC voltage for the electric consumer.
Claims24
1-19. (canceled)
A system for supplying power to an electrical device, the system comprising:
- a DC source;
- and
- a plurality of DC/DC converters, wherein inputs of the DC/DC converters are serially connected to the DC source via an electrical conductor and wherein outputs of the DC/DC converters are connected in parallel to the electrical device,
- wherein the plurality of DC/DC converters receive a high DC voltage from the DC source via the electrical conductor and convert the high DC voltage to a lower DC voltage, the DC/DC converters being spaced for cooling by an ambient medium surrounding the DC/DC converters without an active cooling mechanism
- wherein an input side of each DC/DC converter comprises a resistive load to dissipate power when the electrical device is not consuming power.
-41. (canceled)
A system for supplying power to a remote electrical device, the system comprising:
- a DC source;
- a plurality of DC voltage converters each having an input serially connected to the DC source via a conductor and each having an output connected to the remote electrical device,
- wherein an input side of each DC converter includes a resistive load to dissipate power from the DC source before and after the remote electrical device consumes power.
A DC converter connected to a remote DC source, the DC converter delivering a converted voltage to at least one electric consumer via a cable connection, wherein the DC converter comprises:
- a plurality of DC converter components, each of said DC converter components being, on an input side, serially connected to the remote DC source and, on an output side, connected in parallel to the cable connection so as to provide the converted DC voltage for the electric consumer,
- each DC converter component having on the input side thereof a power dissipation path and a power conversion path,
- the power dissipation paths being configured to distribute power from the remote DC source before the power conversion paths operate to provide the converted DC voltage to the electric consumer.
A power delivery system, comprising:
- a plurality of redundant DC/DC power converters coupled in serial to a DC source, each redundant DC/DC power converter being configured to receive a DC voltage from the DC source and to provide a converted DC output voltage,
- wherein converted DC output voltages provided by the redundant DC/DC power converters are combined in parallel,
- wherein converted DC output voltages provided by the redundant DC/DC power converters are selectively increased to compensate for failed redundant DC/DC power converters.
