Source
A switching arrangement for a motor vehicle powered at least partially electrically, including at least one inverter for converting a DC voltage of a high-voltage battery into a multi-phase AC voltage for a travel drive, at least one intermediate circuit capacitor connected to the inverter, and at least one pre-charge resistor, wherein, in a pre-charge mode, the pre-charge resistor serves to prevent current spikes during charging of the at least one intermediate circuit capacitor and, in a heating mode, serves for heating a coolant, wherein electrical current flows through the inverter in both the pre-charge mode as well as in the heating mode.
