Fault analysis of dual active bridge converters
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012The reliability of bidirectional dc-dc converters is a critical issue in many applications where the power flows from or to energy storage systems regularly, such as automotive applications and standalone power systems. This paper addresses dual active bridge converters faulty operation and proposes a fault detection method.

Battery Emulation Using Dual-Active Bridge Converter
2019 National Power Electronics Conference (NPEC), 2019A Battery Emulator(BE) is a platform that can mimic the behavior of an actual battery in real-time. In a typical BE system, a discretized battery model running on a digital platform controls a power interface hardware capable of transferring power to a device connected to it.

IEEE Transactions on Circuits and Systems I: Regular Papers
Hybrid-bridge based dual-active-bridge (DAB) converter comprised of three-level (3L) and two-level (2L) full-bridge (FB) is promising to be a good candidate for medium voltage DC (MVDC) grids. By applying a corresponding modulation strategy proposed in this paper with multiple working patterns, a wide voltage conversion gain can be obtained.

A Novel Dual Phase Shift Modulation for Dual-Active- Bridge Converter
2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019The isolated dual active bridge (DAB) dc-dc converter with conventional dual-phase-shift (DPS) modulation exhibits large variations of currents under a small change of phase shift ratio at light load and larger peak current and reactive power at non-heavy load. To solve this problem, this paper proposes a novel dual phase shift (NDPS) modulation method

An improved dual active bridge DC/DC converter
2001 IEEE 32nd Annual Power Electronics Specialists Conference (IEEE Cat. No.01CH37230), 2002This paper proposes a novel control scheme for a dual active bridge (DAB) DC/DC converter. The proposed control scheme eliminates the large feedback energy problem existing in previous DAB converters and achieves ZVZCS of all switches. The efficiency and output capacitor current ripple are improved.

Parasitic Resistance Effect on Dual Active Bridge Converter
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019In this paper, the effect of the parasitic resistance on the operation of the dual active bridge (DAB) converter is investigated. Analytical equations of the input-output voltage characteristic for the single phase shift (SPS) and the triangular current (TC) modulation techniques, that consider the parasitic resistance on the secondary side, are ...

Analysis of parallel-serial dual active bridge converter
2014 International Power Electronics and Application Conference and Exposition, 2014A parallel-serial dual active bridge (PSDAB) circuit is presented in the paper to improve the efficiency under the circumstances of high-voltage ratio transformation. The proposed PSDAB circuit is constructed by the paralleled low-voltage terminals of the two dual active bridges (DABs) and the serial high-voltage terminals of the DABs.
