Abstract (en)
[origin: WO2022268358A1] The invention relates to a method for operating a drive system, comprising a plurality of inverters, wherein a respective electric motor is fed from the AC-voltage-side terminal of the respective inverter, wherein the DC-voltage-side terminals of the respective inverters are connected in parallel with one another and said parallel circuit is connected to the DC-voltage-side terminal of a rectifier, the respective inverter having respective semiconductor switches which are driven in accordance with a respective pulse width modulation, the inverters being designed as bus subscribers in a data bus to which a module designed as a master, is also connected. In a first method step, a respective bus address is allocated to each inverter and then, in a second method step, a time offset of the first switching edge, that is to say a starting time (t_i), of its pulse-width modulation, which time offset is related to a synchronization signal, is allocated to each inverter.
