Abstract
The invention relates to an electrical drive system of a hybrid vehicle, comprising: a traction battery (), a high-voltage intermediate circuit (), a pulse-controlled inverter () which is coupled to the high voltage intermediate circuit (), an electrical machine () which is coupled to the pulse-controlled inverter (); a DC-to-DC converter () which is coupled to the pulse-controlled inverter () and the high-voltage intermediate circuit () and is designed to convert a high voltage (UE) from the high-voltage intermediate circuit () into a low voltage (UA) for a vehicle electrical system; a low-voltage battery () which is coupled to the DC-to-DC converter (); a plurality of selectively-connectable electrical consumers () of the vehicle electrical system, which are coupled to the low-voltage battery () and the DC-to-DC converter (); and a control device () which, in the event of a traction battery failure, is designed to operate the DC-to-DC converter () in a current-controlled manner using the electrical machine so as to supply said vehicle electrical system consumers ().
