Analysis of Leakage Inductance Effect and Loss Calculation of DAB Using Single‐Phase Shift Modulation Scheme

open access: yesIET Circuits, Devices &Systems, Volume 2025, Issue 1, 2025.
The swift progression of electric vehicles (EVs) presents significant prospects for the enhanced integration of sustainable energy in the automotive industry. The installation technique and cost‐effectiveness of on‐board chargers (OBCs) have contributed to their increasing popularity as a feasible option for EVs. Moreover, there exists a growing demand

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

open access: yesIET 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.

Resonant technique for bidirectional flyback converter

open access: yesElectronics Letters, 2009
Proposed is an improvement of the bidirectional flyback topology, proposing a resonant inversion of the output polarity voltage. The topology is applied to supply high pressure sodium lamps with a low frequency symmetrical square waveform, in order to avoid the acoustic resonance phenomenon occurrence.
