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.

Control device and method for discharging a DC link capacitor, power converter, and vehicle

Driver unit for a voltage-controlled switching element, includes a first output terminal for connecting a control terminal of the switching element, a second output terminal for connecting a further terminal of the switching element, an output stage section having a high-side terminal and a low-side terminal and being controllable to connect one of its terminals to the first output terminal of the driver unit based on a control signal representative switching the switching element, and a DC conversion section configured to supply the output stage section and to convert an input voltage into a positive first voltage between the high-side terminal and the second output terminal of the driver unit and into a positive second voltage between the second output terminal of the driver unit and the low-side terminal.
