| Zusammenfassung: | A method is for precharging a second network section with electrical energy from a first network section of a DC network. In an initial state, an initial voltage prevailing in the second network section is lower than a DC voltage prevailing in the first network section. At a first point in time, the two network sections are connected via a resistor current path having a precharging resistor. At a subsequent second point in time, as soon as the voltage in the second network section is between the initial voltage and the DC voltage, the two network sections are connected via a semiconductor switch which is situated parallel to the resistor current path and is operated in a clocked mode or in a linear mode as a controllable resistor. |
