Abstract
Przedmiotem zgłoszenia jest wielopoziomowy przekształtnik kaskadowy o obniżonej stromości zmian napięcia wyjściowego du/dt i sposób jego sterowania. Każda gałąź przekształtnika (GP) zawiera obwód rezonansowy (LrCr) składający się z dławika rezonansowego (Lr) oraz kondensatora rezonansowego (Cr), przy czym wejście dławika rezonansowego (Lr) jest połączone z zaciskiem wyjściowym pierwszej gałęzi tranzystorowej (GT1) pierwszego mostka tranzystorowego (H1), a wyjście dławika rezonansowego (Lr) jest połączone z wyjściem przekształtnika (WY), a kondensator rezonansowy (Cr) jest z jednej strony połączony z zaciskiem wyjściowym drugiej gałęzi tranzystorowej (GT2) ostatniego mostka tranzystorowego (Hn), a z drugiej strony jest połączony z wyjściem dławika rezonansowego (Lr).
