Abstract
A circuit arrangement for charging a DC link capacitor with electrical energy from a charging battery includes a first switching element. The first switching element can optionally electrically connect a first connection contact of the circuit arrangement for the charging battery to a second connection contact of the circuit arrangement for the DC link capacitor. The circuit arrangement also includes an electrical pre-charging resistor that can connect in parallel with the first switching element. The circuit arrangement also includes two second switching elements that can be connected in series with the pre-charging resistor and in parallel with the first switching element.
