Claim:
1. An inverter for an electric machine configured to be selectively operated as at least one of a motor and a generator for a hybrid vehicle, comprising: at least one output stage unit for producing a connection between the electric machine configured to be selectively operated as at least one of a motor and a generator and a power supply network; a control unit for controlling the at least one output stage unit; a supply unit, which is independent of the power supply network, for the power supply of the at least one output stage unit; at least one emergency operation control assigned to the at least one output stage unit for controlling the at least one output stage unit in the fault case; and at least one emergency operation supply assigned to the at least one output stage unit for generating a power supply for the at least one output stage unit from the power supply network in the fault case; wherein if the electric machine is selectively operated in a motor operation, the electric machine is supplied with power from the power supply network, and wherein if the electric machine is selectively operated in a generator operation, the electric machine, in reverse, feeds electrical power into the power supply network.
