1. A network (105) for supplying an operating voltage (110) for an electric vehicle (100), the network (105) comprising:
an energy supply interface (115) configured to connect the network (105) to a vehicle battery (135) and/or to a vehicle fuel cell of the electric vehicle (100);
an inverter (120) having a first inverter connection (140) configured to connect the inverter (120) to the energy supply interface (115) and having a second inverter connection (145) configured to connect the inverter (120) to an energization interface (125) and, wherein the inverter (120) is configured to convert a DC voltage applied to the first inverter connection (140) to an AC voltage and to supply same at the second inverter connection (145);
wherein the energization interface (125) configured to energize a unit connected to the energization interface (125); and
a soft starter (130) having a first soft starter connection (150) configured to connect the soft starter (130) to the second inverter connection (145) and a second soft starter connection (155) configured to connect the soft starter (130) to an additional drive (160) of the electric vehicle (100), wherein the soft starter (130) is configured to reduce an input voltage applied to the first soft starter connection (150) and to supply the operating voltage (110), which is reduced compared to the input voltage, at the second soft starter connection (155).
