Analysis of parallel-serial dual active bridge converter

2014 International Power Electronics and Application Conference and Exposition, 2014
A 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.

A review of bidirectional dual active bridge converter

2012 9th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2012
To have a systematic synthesis and galvanic isolation, it is common to use a full-bridge bidirectional DC-DC converter which is sometimes called dual active bridge. A comparative evaluation of full-bridge based bidirectional DC-DC converter is presented in this paper.

Maximum efficiency point tracking algorithm for dual active bridge converters

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
This paper presents an algorithm for seeking the most suitable operating point and the maximum efficiency in respect of the operating conditions in a dual active bridge converter. The method is the most suitable for half-bridge variants of the dual active bridge since the previously presented modulation methods are derived only for full-bridge ...

A Novel Dual Phase Shift Modulation for Dual-Active- Bridge Converter

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
The 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
