Comparative Evaluation of Soft-Switching, Bidirectional, Isolated AC/DC Converter Topologies
(2012)2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC)For realizing bidirectional and isolated AC/DC converters, soft-switching techniques/topologies seem to be a favourable choice as they enable a further loss and volume reduction of the system. Contrary to the traditional dual-stage approach, using a power factor corrector (PFC) stage in series with a DC/DC isolation stage, we showed recently that the same functionality can be achieved under full soft-switching operation using a single-stage ...Conference Paper -
Switching Control Strategy for Full ZVS Soft-Switching Operation of a Dual Active Bridge AC/DC Converter
(2012)2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC)A switching control strategy to enable Zero-Voltage-Switching (ZVS) over the entire input-voltage interval and the full power range of a single-stage Dual Active Bridge (DAB) AC/DC converter is proposed. The converter topology consists of a DAB DC/DC converter, receiving a rectified AC line voltage via a synchronous rectifier. The DAB comprises primary and secondary side full bridges, linked by a high-frequency isolation transformer and ...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
