This paper focuses on extending an urban DC traction substation functionality by means of an additional power converter interface (PCI). In particular, by enabling bidirectional energy exchange between LV DC traction grid, AC grid and V2G chargers. Among other things, the presented material compares general attributes of the most promising DC/DC converters that can be used in a PCI, meet the requirements of galvanic isolation and can operate in a wide voltage range. Based on the literature, the application suitability of typical PCI structures and isolated DC/DC converters was made. In addition, the principles of power flow in the power converter interface that connects an AC grid, DC traction grid, V2G chargers and PV source are discussed.

Niniejszy artykuł koncentruje się na zagadnieniach związanych z rozszerzeniem funkcjonalności miejskich podstacji trakcyjnych prądu stałego za pomocą dodatkowych interfejsów energoelektronicznych, w szczególności umożliwiających dwukierunkową wymianę energii między trakcją, siecią i ładowarkami V2G. W prezentowanym materiale porównano między innymi ogólne atrybuty połączeń przetwornic DC/DC i aktywnych prostowników rewersyjnych, spełniających wymagania separacji galwanicznej i pracy w pełnym zakresie zmian napięcia trakcyjnego. Na podstawie literatury scharakteryzowano również przydatność typowych izolowanych przetwornic DC/DC. Ponadto omówiono zasady przepływu mocy w interfejsie łączącym sieć AC, trakcję DC, ładowarkę V2G i źródło PV.
