This paper presents a new step-up DC/DC converter topology to be used for distributed energy systems. The topology contains a voltagefed quasi-Z-source inverter with continuous input current, a high-frequency step-up isolation transformer and a voltage doubler rectifier. Main operating modes of the converter are explained and steady state analysis of the voltage-fed quasi-Z-source inverter is provided. Guidelines for selection of the converter’s components are discussed and design generalizations are provided in the final part of the paper.

W artykule przedstawiono nowy układ przekształtnika DC-DC podwyższającego napięcie, przeznaczony do zastosowania w rozproszonych systemach energetycznych. Przekształtnik zawiera falownik napięcia typu qZ, działający w obszarze ciągłego prądu wejściowego, podwyższający transformator izolacyjny wysokiej częstotliwości oraz prostownikowy podwajacz napięcia wyjściowego. Rozpatrzono główne tryby pracy przekształtnika oraz przeprowadzono analizę stanów statycznych falownika napięcia typu qZ. W końcowej części artykułu zamieszczono ogólne wytyczne do projektowania i doboru elementów.
