  "textContent": "Provided is a DC/DC converter station having an input series-output parallel structure. The converter includes: a plurality of DC converters with input terminals connected to each other in series and output terminals connected to each other in parallel; an auxiliary power supply connected to at least one secondary-side conversion unit among the plurality of DC converters and supplying initial charging power; and a control unit controlling the auxiliary power supply and performing initial charging of the converter station. The control unit is configured to charge a secondary-side capacitor within the secondary-side conversion unit via the auxiliary power supply and to charge a primary-side capacitor within a primary-side conversion unit within the DC converter via a transformer within the DC converter based on voltage of the secondary-side capacitor.",
