T-source inverter

Modern renewable generation systems and uninterruptible power supply (UPS) applications need smart and integrated power converters ensuring high efficiency of power conversion, reliability and low investment costs. The aim of the paper is to show the possibility of realization of buck-boost inverter similar to Z-source inverter but with use of high frequency transformer with low leakage inductance. Theoretical analysis as well simulation and experimental results are shown in the paper. Streszczenie. Uklady generowania i kondycjonowania energii wymagają zintegrowanych przeksztaltnikow energoelektronicznych o jak najwyzszej sprawności przetwarzania oraz niezawodności. Celem referatu jest pokazanie mozliwości realizacji ukladu podobnego do Z-falownika. Dlawiki czwornika wejściowego Z-falownika zastąpiono transformatorem impulsowym o malej indukcyjności rozproszenia i o zwartych zaciskach dolnych, ktory razem z jednym kondensatorem tworzy obwod wejściowy typu T. Pokazano analize teoretyczną nowego ukladu oraz wyniki badan.(Falownik typu T)
