Carregador de baterias de íon-lítio baseado nas topologias Voltage Source Inverter (VSI) e Buck
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia ElétricaEngenharia ElétricaUTFPR, 2021-12-03)
This work presents the study of an AC-DC converter with power factor correction for charging electric vehicle batteries. Due the widespread exploration of fossil fuels and the great risks that these provide to the population’s ...
Electricity sector in the Galapagos Islands: Current status, renewable sources, and hybrid power generation system proposal
(2019-07-01)
The electricity sector in the Galapagos Islands is heavily dependent on fossil fuels for electricity generation but only a few renewable sources are used for such a purpose in this archipelago. Therefore, this work aims ...
On optimizing micropower MOS regulated cascode circuits on switched current techniques
(1998-01-01)
Trade-off between settling time and micropower consumption in MOS regulated cascode current sources as building parts in high-accuracy, current-switching D/A converters is analyzed. The regulation-loop frequency characteristic ...
Implementação de conversor CC-CC com alto ganho de tensão e saída em corrente
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de EletrotécnicaEngenharia ElétricaUTFPR, 2015-07-01)
The photovoltaic power generation stands out in the search for renewable electricity sources less harmful to the environment and especially closer to the largest energy consumers. This is due to the fact that photovoltaic ...
Estudo e projeto de um conversor boost dois níveis
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2015-11-17)
