Estudo de paralelismo de alimentadores radiais de distribuição sob o enfoque das perdas de energia
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2016-11-17)
This work presents a study about how the electric energy loss in radial feeder distributers, that belongs to only one substation. The energy loss were analyzed with the feeders operating radially and in parallel. With 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 need of subsidy for the implementation of photovoltaic solar energy as supporting of decentralized electrical power generation in Brazil
(2013-01-08)
The growing demand for electrical power and the limited capital invested to provide this power is forcing countries like Brazil to search for new alternatives for electrical power generation. The purpose of this paper is ...

Programa de eficiência energética industrial priorizando o consumo desagregado no diagnóstico energético
(Universidade Tecnológica Federal do ParanáPato Branco, 2011-11-23)
This work is the development of an energy efficiency program, where the energy diagnosis (or audit of potential energy efficiency), was performed using the method of consumption disaggregated into end uses well as other ...
Low-cost PWM speed controller for an electric mini-baja type vehicle
(2007-01-01)
This paperwork presents a Pulse Width Modulation (PWM) speed controller for an electric mini-baja-type car. A battery-fed 1-kW three-phase induction motor provides the electric vehicle traction. The open-loop speed control ...
