New Triple-Output Quad-Active-Bridge DC/DC Converter Employing a Four-Leg Inverter Input Stage
(2023)2023 26th International Conference on Electrical Machines and Systems (ICEMS)Charging stations for electric vehicles require electrical isolation between the charging ports. Therefore, this paper proposes a multi-port DC/DC converter structure that combines three conventional dual-active bridge converters (DABCs) where the primary side switching stages are integrated into a single four-leg inverter, and three individually isolated output ports (4L3) are provided. This quad-active bridge converter (QABC) structure ...Conference Paper -
Novel Bidirectional Single-Stage Isolated Three-Phase Buck-Boost PFC Rectifier System
(2023)2023 IEEE Applied Power Electronics Conference and Exposition (APEC)Future three-phase ac-dc converter systems ideally allow for bidirectional power flow, provide high-frequency isolation, and feature buck-boost capability. Further, high efficiency and high compactness and the applicability of standard half-bridge and/or three-phase full-bridge (B6) semiconductor arrangements are crucial aspects. This Paper proposes a novel converter concept that employs B6-type circuits on the input and on the output ...Conference Paper
