Contribuições ao estudo de conversores CC–CC com processamento parcial de energia aplicados a sistemas fotovoltaicos
(Universidade Federal de Santa Maria, 2017-12-18)
This work presents some conceptual and practical contributions about the use of series-regulated
DC/DC converters in multi-string photovoltaic systems, which have been presented in the literature
as capable of performing ...
Inversor multiníveis quasi-Z-source com fonte CC única e compartilhamento de potência ativa entre os módulos
(Universidade Federal de Santa Maria, 2019-07-26)
Due to its ability to provide Maximum Power Point Tracking (MPPT) control and independent
regulation of the DC bus voltage, this makes the inverter quasi-Z-Source (qZS) an attractive
candidate for applications in ...
Microinversores baseados na topologia meia-ponte isolada alimentada em corrente
(Universidade Federal de Santa Maria, 2018-07-25)
The Microinverter is an inverter sized to meet individual solar panels, usually consisting of two stages, one DC-DC stage and another CC-AC stage. For the first stage of the DC link microinverter, the isolated current-fed ...
Conversores compostos para o interlink entre os barramentos de baixa e extrabaixa tensão de nanorredes CC
(Universidade Federal de Santa Maria, 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 ...
