Abstract
A method for shutting down an electric machine having a pulse-controlled inverter in the event of a malfunction. Undesirable side effects during shut-down of the electric machine may be minimized and the regular machine operation may be maximized when the electric machine is first switched to a disconnect mode in which all switches of the pulse-controlled inverter are open and subsequently is switched to a short-circuit mode in which the switches connected to the high potential are open and the switches connected to the low potential are closed.
