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, ...
Optimal asymmetry for cascaded multilevel converter with cross-connected half-bridges
(IEEE, 2015)
DC-AC conversion has been revolutionized by multi-level converters due to their high power quality, high modularity and high voltage operation with standard semiconductors. New multilevel topologies, voltage asymmetries ...
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 ...
