Dual‐Active‐Bridge LC Resonant DC–DC Converter With an Auxiliary Boost Arm for Battery Energy Storage Systems

IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.
This study presents a dual‐active‐bridge (DAB) LC resonant DC–DC converter for battery energy storage systems. The proposed converter adds an auxiliary bridge arm to the traditional full‐bridge (FB) LC resonant converter as a boost arm. It features two efficient operating modes: a charging low‐gain (CLG) mode and a discharging high‐gain (DHG) mode.

An Isolated SEPIC‐Based AC‐AC Converter for Voltage Sag/Swell Mitigation

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
ABSTRACT This paper proposes a high‐frequency isolated buck‐boost AC‐AC converter based on the single‐ended‐primary‐inductance‐converter (SEPIC) topology and its extension circuit with bipolar output. The proposed converters can achieve a wide range of voltage step‐down and step‐up operations with both same‐ and reversed‐phase outputs.
