Abstract
An inverter for an electric machine, and a method for operating the inverter, has at least one output stage unit for producing a connection between the electric machine and a power supply network, a control unit for controlling the output stage unit, a supply unit independent of the power supply network for power supply of the output stage unit, at least one emergency operation control assigned to the output stage unit for controlling the output stage unit such that switching elements are switched into a short circuit operation, at least one emergency operation supply assigned to the output stage unit for generating a power supply from the power supply network, and a coordination control, which activates or deactivates the emergency operation control as a function of a status signal of the independent supply unit and a standby signal of the control unit.
