Abstract
An electrical on-board power system for an electrically driven transportation vehicle having a traction battery with a first battery terminal and a second battery terminal, a first current path between the first battery terminal and a first terminal, and a second current path between the second battery terminal and a second terminal. An electrical or electromagnetic first switch is connected in the first current path and an electrical or electromagnetic second switch is connected in the second current path. The on-board power system has a DC-to-DC voltage converter connected at output to a low-voltage system, wherein a first input of the DC-to-DC voltage converter is connected to a first tap in the first current path and the first switch, and a second input of the DC-to-DC voltage converter is connected to a second tap between the second switch and the second load terminal.
