  • Inverter arrangement, electric drive system, and method for discharging a DC link capacitor in an inverter arrangement
    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.

  • Circuit arrangement for the temperature-dependent actuation of a switching element
    Patent number: 10992296
    Abstract: The invention relates to a circuit arrangement (100) for the temperature-dependent actuation of a first switching element (S1), comprising an input terminal (EA) for accepting an input potential, an output terminal (AA) for transferring an output potential to a first control terminal (G1) of the first switching element (S1), and a temperature-dependent component (RT) which is connected between the input terminal (EA) and the output terminal (AA).
