Contribuições na modelagem e projeto de controladores para conversores CC-CC do tipo boost em arquitetura celular operando no modo de condução crítica
(Universidade Estadual Paulista (Unesp), 2020-05-28)
Este trabalho aborda o desenvolvimento e a avaliação de modelos matemáticos aplicados à análise e projeto do conversor CC-CC do tipo Boost, operando em modo de condução crítica (MCCr). Por meio de análises qualitativas e ...
Kinetic and temporospatial gait parameters in a heterogeneous group of dogs
(2016-01-04)
Background: A prime concern of the gait analysis in a heterogeneous group of dogs is the potential influence of factors such as individual body size, body mass, type of gait, and velocity. Thus, this study aimed to evaluate ...
Módulo para gerenciamento de pré-carga de capacitores
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia EletrônicaUTFPR, 2019-12-12)
This project presents a capacitor pre-charge and discharge system, based on a soft-start strategy with a step-down DC-DC converter. The system aims to mitigate the inrush current effect on a step-up converter. The inrush ...
High-Performance Control of a DC–DC Z-Source Converter Used for an Excitation Field Driver
(Institute of Electrical and Electronics Engineers, 2012-06)
The electromechanical interface is a Synchronous Machine because its field winding permits direct management of the magnetization during speed variations. For systems with a common dc-link for the drive and excitation ...
Data-driven control of DC-DC power converters
In this thesis we develop a data-driven approach to the control design of power convert- ers. We show that, given a set of measured data containing information about variables of interest (duty cycle as the input and ...
Estratégias de controle para correção da distorção harmônica da corrente de entrada do retificador Boost em MCD entrelaçado em série
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Sistemas de EnergiaUTFPR, 2019-05-15)
This work proposes two control techniques based on variable duty-cycle for the serial interleaved boost rectifier. The purpose of the control strategies is to increase the power factor and efficiency of the rectifier by ...
