Method for controlling inverter mounted in drive train of motor vehicle, involves providing electrical voltage when inverter is switched to tension-free switching state and tension switching state within pulse width modulation period

摘要

The method involves supplying a multi-phase electric current (I-U,I-V,I-W) to an electric machine (14) of an inverter (10). The inverter is controlled by the successive different switching states of the controllable switches (S-HA-S-HC,S-LA-S-LC) to provide an electrical voltage in the form of a voltage space vector. The electrical voltage is provided when the inverter is switched to the tension-free switching state and tension switching state within a pulse width modulation period. Independent claims are included for the following: (1) device for controlling inverter; and (2) drive train of motor vehicle.
