Abstract
The invention relates to a method () for operating an inverter (), comprising the steps of: —controlling () the inverter () for transferring the inverter (), the intermediate circuit capacitor () and the electric machine () into a safe state, in particular into a free-wheeling mode (FW). The method is characterized by the following steps: determining () a cut-off vector; controlling () the inverter () corresponding to the cut-off vector; determining () the three phase currents (Iu, Iv, Iw) of the electric machine (); controlling () the inverter () into the free-wheeling mode (FW) if the three phase currents (Iu, Iv, Iw) determined fall below a predefined current threshold value (Is).
