Claim 0:
1. A converter comprising:
a DC split link with a positive line, a floating midpoint, and a negative DC line;
a first DC capacitance arranged between the positive line and the floating midpoint;
a second DC capacitance arranged between the negative DC line and the floating midpoint;
a first resistor arranged in parallel to the first DC capacitance;
a second resistor is arranged in parallel to the second DC capacitance;
a first switchable contact is arranged in series with the first resistor; and
a second switchable contact is arranged in series with the second resistor,
wherein the first and the second resistors are configured to be engaged at least during a pre-charge phase of the converter, and
wherein the first and second switchable contacts are of type “normal-on”.
