Uma aplicacao da celula de comutacao ZVS-PWM-GEPAE ao conversor DC-AC
(1996-05-01)
This work presents the design and procedure of a DC-to-AC converter using a ZVS Commutation Cell developed by Barbi and Martins (1991) and applied to the family of DC-to-DC PWM converters. Firstly, we show the cell applied ...
Modelagem de uma fonte de corrente contínua controlada utilizando conversor buck
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2018-11-01)
Current sources provide the value of current regardless of the load of their connected charge. It has utmost importance for every electrical engineer student, since it is referring to a major subject of graduation. The ...
Comportamento da distorção harmônica de corrente na rede em um conversor de frequência em função da variação da carga mecânica no motor
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia ElétricaUTFPR, 2018-06-11)
The present work presents the simulation of a frequency converter topology of the Voltage Source Inverter (VSI) type. Harmonic distortion concepts and their respective effects are presented, concepts about norms that govern ...
The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
Programmable PFC based hybrid multipulse power rectifier for utility interface of power electronic converters
(2005-12-01)
In this paper it is proposed a novel hybrid three-phase rectifier capable to achieve high input power factor (PF), and low total harmonic distortion in the input currents (THDI). The proposed hybrid high power rectifier ...

Desenvolvimento de conversor bidirecional isolado para controle de carga e descarga de bancos de baterias
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2018-02-21)
The bidirectional and isolated converters discussed in this work are of great interest for applications such as UPS’s (Uninterrupted Power Supply) and hybrid generation power systems. They allow the charging and discharging ...
Sistema de armazenamento e geração de energia para locais de consumo remotos
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia EletrônicaEngenharia EletrônicaUTFPR, 2016-11-11)
This work proposes the use of the converter Back to Back to maintain constant the voltage in the load on situations when the grid suffers from fluctuations or voltage drops. For this, the converter will have on your DC bus ...
