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.

20. A system for supplying power to an electrical device, the system comprising:
-
a DC source;
a plurality of DC/DC converters, wherein inputs of the DC/DC converters are connected to the DC source via an electrical conductor and wherein outputs of the DC/DC converters are connected 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 without a cooling mechanism that is needed when an amount of DC/DC converters less than the plurality of DC/DC converters are implemented to convert the high DC voltage to the lower DC voltage, and wherein an input side of each DC/DC converter comprises a resistive load to dissipate power when the electrical device is not consuming power. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
