Claim 0:
1. A method 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 being relatively lower than a DC voltage prevailing in the first network section, the method comprising:
connecting, at a first point in time, the first network section and the second network section via a resistance current path including a precharging resistor; and
connecting, at a subsequent second point in time when the voltage in the second network section lies between the initial voltage and the DC voltage, the first network section and the second network section via a semiconductor switch arranged parallel to the resistance current path and operated in a clocked mode.
