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 ...
Estudo, análise e implementação de uma metodologia para otimização de rendimento em sistemas compostos por conversores em paralelo
(Universidade Federal de Santa Maria, 2014-09-05)
This PhD Dissertation proposes a new methodology for efficiency maximization in systems
comprising parallel converters. For a given number of system converters, their maximum
power and their efficiency curves, the proposed ...
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 ...
