Software para projeto e análise de conversores estáticos
(Universidade Federal de Santa MariaBrasilUFSMUFSM Cachoeira do Sul, 2019-12-11)
This paper presents the development of a tool to assist in the design and analysis of simple static converters such as buck, boost, buck-boost converter for both operation modes and
flyback for DCM. Initially, a bibliographic ...
Reactive Power Compensation Technologies: State-of-the-Art Review
(2005)
This paper presents an overview of the state of the art in reactive power compensation technologies. The principles of operation, design characteristics and application examples of Var compensators implemented with thyristors ...
Voltage source active power filter, based on multi-stage converter and ultracapacitor dc-link
(IEEE, 2003)
A multi-stage inverter using three-state converters is being analyzed for active filter and static var compensator applications. Each phase of the converter is composed of four three-state converters, all of them connected ...
Metodologia de projeto otimizado de conversores estáticos aplicados a sistemas fotovoltaicos
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2017-08-11)
This work proposes an optimized design methodology for static converters applied to
systems where the processed energy is discontinuous and/or variable over time. It will be
demonstrated that in these cases, it is not ...
Analysis, design and implementation of single-stage high-frequency-isolated DC-AC flyback converters
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2016-09-30)
This thesis proposes the analysis of two single-stage high-frequency isolated converters suited for grid-tied applications. Firstly, a new modulation strategy to the bidirectional flyback converter with differential output ...
