Method for actuating electrical induction machine by power electronics in motor vehicle, involves adjusting operating mode of machine in response to adjusted speed range and/or fault condition of machine
Method for actuating electrical induction machine by power electronics in motor vehicle, involves adjusting operating mode of machine in response to adjusted speed range and/or fault condition of machine
The method involves providing a set of controllable power switches that are connected to form phase conductors. A polyphase machine (14) is allowed to have a set of potentials, and a direct current voltage. A set of bridge circuits is actuated in a mode such that the machine is provided with a number of poles. The set of bridge circuits is driven in another mode. An operating mode of the machine is adjusted in response to an adjusted speed range and/or fault condition of the machine. Independent claims are also included for the following: (1) a device for actuating an electrical induction machine (2) a motor vehicle power train.
