  • Control device and method for discharging a DC link capacitor, power converter, and vehicle
    Patent number: 11881763
    Abstract: In a control device for discharging a DC link capacitor by means of a discharging device including a load resistor and a switch element connected in series with the load resistor, the control device includes a generator unit, which is configured to generate a pulse width-modulated actuation signal for the switch element with an ascertained duty cycle, and a control unit, which is configured to ascertain the duty cycle in such a way that, in the time average, a desired discharge current flows through the load resistor.
