Triangular/trapezoidal current mode for high step ratio modular multilevel dc-dc converter
(2022)
Recent developments in dc powered technologies have increased interest in highly efficient dc-dc converters, especially at high voltage and high-step voltage ratios. Modular multilevel converters (MMCs) are an attractive ...
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 ...
Triangular Current Mode for High Step Ratio Modular Multilevel DC-DC Converter
(IEEE, 2018)
DC networks have generated much interest in recent years, from transmission in high voltage to their use in distribution systems. One of the major challenges is to replace the high efficient and reliable ac transformer, ...
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 ...
Passivity-based control for battery charging/discharging applications by using a buck-boost DC-DC converter
(IEEE Computer Society, 2018)
In this paper, a passivity-based control (PBC) theory is applied to control a battery energy storage system (BESS) under current control mode by employing a bidirectional buck-boost DC-DC converter. The proposed controller ...
Estudo, controle e modelagem do conversor dual active bridge (dab) para conexão no sistema elétrico de potência
