Uma nova metodologia de projeto para otimização do volume do converosr boost PFC
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2009-03-27)
This work investigates the influence of operation point (Δi @ fs) in the final volume of PFC boost converter. The boost inductor, EMI filter and thermal heatsink are the elements which main influences in the converter ...
Power Factor Correction Boost Converter Based on the Three-State Switching Cell
(Institute of Electrical and Electronics Engineers (IEEE), 2012-03-01)
The need for solid-state ac-dc converters to improve power quality in terms of power factor correction, reduced total harmonic distortion at input ac mains, and precisely regulated dc output has motivated the investigation ...

Dc-dc 3ssc-a-based boost converter: Analysis, design, and experimental validation
(2021-10-01)
A detailed analysis and validation of the DC-DC boost converter based on the three-state switching cell (3SSC) type-A are presented in this paper. The study of this topology is justified by the small amount of research ...
NOVEL ISOLATED MULTI-PULSE RECTIFIERS WITH LOW CURRENT DISTORTION USING THREE-PHASE HALF-CONTROLLED BOOST CONVERTERS
(Ieee, 2015-01-01)
Since the AC-DC conversion is widely spread in power sources, this work proposes a novel strategy of multi-pulse topologies, associated to the half-controlled boost-based rectifier, which has the follows main advantages: ...
