Abstract:
A converter includes 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 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. The first and the second resistors are configured to be engaged during a pre-charge phase of the converter.
