• An Efficient Non-Inverting Buck-Boost Converter with Improved Step Up/Down Ability 

      Abdel-Rahim, Omar; Chub, Andrii; Blinov, Andrei; Vinnikov, Dmitri; Peftitsis, Dimosthenis (Peer reviewed; Journal article, 2022)
      In this article, a new non-inverting buck-boost converter with superior characteristics in both bucking and boosting is presented. The proposed converter has some distinct features, such as high step-up/-down ability and ...
    • High Gain DC-AC High-Frequency Link Inverter with Improved Quasi-Resonant Modulation 

      Blinov, Andrei; Korkh, Oleksandr; Chub, Andrii; Vinnikov, Dmitri; Peftitsis, Dimosthenis; Norrga, Staffan; Galkin, Ilya (Peer reviewed; Journal article, 2021)
      This paper presents a high gain pure sine-wave inverter based on the full-bridge DC-AC high-frequency (HF) link cycloconverter topology for telecom or general-purpose applications. The improved quasi-resonant modulation ...
    • Isolated High-Frequency Link PFC Rectifier With High Step-Down Factor and Reduced Energy Circulation 

      Blinov, Andrei; Vinnikov, Dmitri; Romero-Cadaval, Enrique; Martins, João; Peftitsis, Dimosthenis (Peer reviewed; Journal article, 2022)
      This article presents an isolated single-stage ac–dc high-frequency link full-bridge cycloconverter (HFLC) with high conversion ratio. Despite certain advantages, such topologies gen- erally suffer from transformer leakage ...
    • Regenerative Passive Snubber Circuit for High-Frequency Link Converters 

      Blinov, Andrei; Verbytskyi, Ievgen; Peftitsis, Dimosthenis; Vinnikov, Dmitri (Peer reviewed; Journal article, 2021)
      This letter presents a passive snubber circuit for high-frequency link cycloconverters, which typically suffer from voltage oscillations across matrix-stage semiconductor devices. The proposed passive snubber allows for ...
