Abstract

The invention is concerned with a method for operating an electric inverter (13) for driving an electric machine (12), wherein a controller circuit (15) stores a first vector set (18) of command vectors (18') for switching four stator phases (14) of the electric machine (12), while a fault detection unit (21) detects a fault (22) of a predefined fault type. The invention is characterized in that for the fault type a predefined additional vector set (18') of command vectors (V) is provided and the controller circuit (15) continues driving the electric machine (12) in a fault regime mode (20) by switching the inverter (13) on the basis of the additional vector set (18') of command vectors (V), wherein the command vectors (V) of the additional vector set (18') are designed to compensate a spatial component of an electro-magnetic field vector generated by the fault (22) in the electric machine (12).
