  • Patent number: 11011974
    Abstract: The invention relates to the discharging of a DC link capacitor in an inverter arrangement, thereby allowing, for example, a DC link capacitor to be discharged while an electric machine that is connected to the inverters can operate in an idling mode as a safe mode. The DC link capacitor is discharged by very briefly triggering a semiconductor switch within the inverter. According to the invention, the inverter bridge arm with the smallest phase voltage is selected for the very brief triggering process.
