Inverter (9) for an electric machine (1), comprising an input terminal (10) connectable to a DC voltage, a DC link (12) connected to the input terminal (10), an output terminal (11) connectable to stator windings (5) of the electric machine (1) and a controller (22) configured to provide in a pulsing mode pulsing signals causing the inverter (9) to convert the DC voltage into a multiphase AC output voltage at the output terminal (11) and to transfer the inverter (9) from the pulsing mode into an active short circuit mode, characterized in that the controller (22) is configured to control at least one interrupt device (13, 13') being arranged in a line (15, 17) of the DC link (12) to interrupt a current flow along the line (15, 17) transmitting a power from the output terminal (11) to the input terminal (10) if the inverter (9) is transferred from the pulsing mode into the active short circuit mode.
