Abstract: The disclosure provides methods and a power converter arrangement for converting an alternating current (AC) voltage into a direct current (DC) voltage. The power converter arrangement includes: an AC-DC conversion stage being configured to convert an AC voltage into a first DC link voltage at a first DC link and into a second DC link voltage at a second DC link; a DC-DC conversion stage connected to the AC-DC conversion stage, the DC-DC conversion stage being configured to provide the DC voltage based on the first DC link voltage and the second DC link voltage; and a partial-power DC-DC converter coupled between the AC-DC conversion stage and the DC-DC conversion stage, the partial-power DC-DC converter being configured to exchange power between the first DC link and the second DC link.
