Abstract
Official abstract text for this publication.
In a method for operating an at least three-phase electric machine used as a drive assembly in a motor vehicle, which is actuated via an inverter, the inverter including switching elements in the form of half bridges which are in each case electrically connected to a respective phase of the electric machine, when a first switching element of a first half bridge connected to a first phase is permanently closed/opened on account of failure, a second switching element of the first half bridge is permanently opened/closed and, in a first angular range of an electrical rotation, which is uninfluenced by the first phase, all switching elements of the additional half bridges are actuated in the usual manner.
First claim
Opening claim text (preview).
What is claimed is: 1. A control unit for controlling an inverter which actuates an at least three-phase electric machine used as a drive assembly in a motor vehicle, the inverter including switching elements in the form of half-bridges which are each electrically connected to a respective phase of the electric machine, the control unit comprising: means for performing the following in response to the failure of a first switching element of a first half-bridge connected to a first…
