Hybrid Full Bridge-Half Bridge MML Power Converter for HVDC Diode Rectifier Connection of Large Off-Shore Wind Farms
(2018)
The connection of large off-shore wind farms using diode rectifier (DR) units presents important advantages due to the simplicity of the diode rectifier converter, its robustness and weight and loss reduction. Moreover, ...
A new three-phase low THD power supply with high-frequency isolation and 60V/200A regulated DC output
(2001-10-22)
This work proposes a new isolated high power factor 12kW power supply based on an 18-pulse transformer arrangement. Three full-bridge converters are used for isolation and to balance the DC-link currents, without current ...

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 ...
Análise e metodologia de projeto de conversores cc-cc isolados com comutação sob tensão nula: ponte-completa e duplo meia-ponte
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2017-08-10)
This work presents a study of an isolated DC-DC converter with zero-voltage switching (ZVS)
and phase-shifted (PS) applied to full-bridge (ZVS-PS-FB) and double half-bridge converters
(ZVS-PS-DHB). The double half-bridge ...
Método de carga para banco de baterias em fontes ininterruptas de energia que busca garantir o estado de carga completa: corrente pulsada modificado
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2015-02-15)
This Master s Dissertation is proposes the development of a charge management system of a bank of 16 lead-acid batteries with 7Ah load capacity, commonly used in Uninterruptible Power Supplies (UPS). This system aims to ...
27-level converter for electric vehicles using only one power supply
(IEEE, 2010)
The main advantage of asymmetrical multilevel inverters is the optimization of levels with a minimum number of power supplies. However, this optimized multilevel system still needs a large number of isolated and floating ...
Three-Port Full-Bridge Bidirectional Converter for Hybrid DC/DC/AC Systems
(IEEE, 2020)
Sustainable solutions such as renewable energies, distributed generation, energy storage, and electric vehicles require power conversion and advance control techniques. This process is usually done in two stages by more ...
Micro-inverter for integrated grid-tie PV module using resonant controller
(2012-12-11)
Two-stage isolated converters for photovoltaic (PV) applications commonly employ a high-frequency transformer on the DC-DC side, submitting the DC-AC inverter switches to high voltages and forcing the use of IGBTs instead ...
