Abstract
A method, a device and an electrical system for discharging a first electrical network. The first electrical network comprises in particular an intermediate circuit which comprises in particular an intermediate-circuit capacitor. The first electrical network is connected to a second electrical network by means of a DC-DC converter for this purpose. The first electrical network is discharged by means of the DC-DC converter. At the same time, the DC-DC converter transfers electrical energy into the second electrical network. For discharging, the output voltage of the DC-DC converter is set to a first voltage value, which is larger than the nominal voltage of the second electrical network. For discharging, the output voltage of the DC-DC converter is set to the first voltage value for a predefinable first period of time.
