Isolated Buck/Boost Bidirectional DC-Three Phase Topology
(Institute of Electrical and Electronics Engineers, 2016-06)
In this paper a new topology, isolated Buck/Boost bidirectional DC-AC three phase, for interconnecting a DC micro grid with conventional three-phase AC network, is presented. Its operating principle is explained, and a ...
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 ...
Fault-Tolerant Reconfiguration System for Asymmetric Multilevel Converters Using Bidirectional Power Switches
(IEEE, 2009)
Asymmetric multilevel converters can optimize the number of levels by using H-bridges scaled in the power of three. The shortcoming of this topology is that the H-bridges are not interchangeable, and then, under certain ...
POWER CONTROL OF A BIDIRECTIONAL DC BUS FOR FUEL CELLS APPLICATIONS ABSTRACT
(Fondo Editorial EIA - Universidad EIA, 2013-09-27)
This paper proposes a power system for fuel cell applications able to transfer energy from the power source to the load, and to charge an auxiliary storage device using regenerative power flows generated by the load. The ...
Isolated bidirectional DC-DC converter based on the integration of the full-bridge ZVS-PWM and current-fed push-pull converter for DC microgrid applications
(2019)
Esta dissertação de mestrado apresenta a proposta de um Conversor CC-CC Bidirecional Isolado baseado na integração dos conversores CC-CC ZVS-PWM Ponte Completa e Push-Pull alimentado em corrente, grampeado com um conversor ...
Current controller for a bidirectional boost input stage equipped with an LCL (inductance-capacitance-inductance) filter
(Elsevier, 2015-05)
A control strategy for a low resonance frequency LCL filter used in the input stage of dc-dc bidirectional boost converters is proposed. When compared with the classical L filter, an LCL filter allows to obtain a cheaper ...
High integrated battery monitoring system with active balancing up to ±10A
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Elétrica - PPGEECâmpus São Carlos, 2022-02-22)
This master's thesis describes the development, construction, and setup of a flexible and modular, highly integrated battery monitoring system. The electronic unit uses an active balancing process with currents up to ±10A ...
Estudo, controle e modelagem do conversor dual active bridge (dab) para conexão no sistema elétrico de potência
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2022-02-18)
This work proposes to design, analyze and develop a bidirectional DC-DC converter
to perform the interface between a renewable source (wind or solar for example) and a
battery bank so that the power flow through this ...
Conversores compostos para o interlink entre os barramentos de baixa e extrabaixa tensão de nanorredes CC
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2022-07-27)
This thesis presents a study on isolated DC-DC converters for the interface between a
low voltage bus, EBT (48 V), and a low voltage bus, BT (380 V) for a 1.2 kW residential
DC-DC nanogrid. The proposed converter makes ...
