Modulation strategy to operate the dual active bridge DC-DC converter under soft-switching in the whole operating range
(Institute of Electrical and Electronics Engineers, 2011-04)
A new modulation strategy that allows operating the dual active bridge (DAB) dc–dc converter under soft switching in the whole operating range is proposed. This strategy is ruled by imposing a certain modulation index in ...
Analysis of the Transformer Influence on a Three-Phase Dual Active Bridge DC-DC Converter
(Institute of Electrical and Electronics Engineers, 2016-07)
In this work, the impact of the high-frequency transformer on the three-phase dual active bridge DC-to-DC converter operation is investigated, using four transformers with different connections: star-star, delta-delta, ...
Control of a DC-DC Dual Active Bridge Converter in DC Microgrids Applications
(Institute of Electrical and Electronics Engineers, 2021-08)
In this paper, a control strategy for an isolated DCDC dual active bridge converter to adapt different voltage levels in a DC microgrid is proposed. The control strategy allows regulating the output voltage while maintaining ...
Análise e projeto do sistema de controle de um módulo de potência com conversores em cascata aplicado a transformadores de estado sólido
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2016-07-29)
This master thesis present the analysis of a power module with cascaded converters
applied to solid state transformers. The power module is built by an AC-DC input stage,
constituted by full-bridge topology, an DC-DC ...

Open Transistors Fault-Tolerant Schemes of three-Phase Dual Active Bridge DC-DC Converters
(Institute of Electrical and Electronics Engineers, 2021-03)
This work proposes fault-tolerant schemes for open-transistor faults applied to three-phase dual active bridge converters (TPDABC), using different transformers: star-star, delta-delta, and delta-star. The proposal consists ...
A comparative study of Three–Phase Dual Active Bridge Converters for renewable energy applications
(Elsevier, 2017-10)
The influence of different transformers in the operation of a three–phase dual active bridges DC–DC converter is analyzed. The transformers considered have their windings connected in star–star, delta–delta, star–delta and ...
