DC CONVERTER ARRANGEMENT, ELECTRIC VEHICLE, AND METHOD FOR OPERATING A DC CONVERTER ARRANGEMENT

The invention discloses a DC voltage converter arrangement for supplying power to a low-voltage network from a high-voltage network in an electric vehicle. In addition to a DC voltage converter, the DC voltage converter arrangement comprises a supplementary auxiliary power supply. This auxiliary power supply can provide electrical power to the control components of the DC voltage converter. On the other hand, the power supply can also feed electrical energy into the low-voltage network, so that the DC voltage converter can be deactivated when there is low power demand in the low-voltage network.
