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 ...
Electric linear dichroism transients of bent DNA fragments
(American Institute Of Physics, 2013-03-06)
We study the effect of translational-rotational hydrodynamic coupling on the transient electric linear dichroism of DNA fragments in aqueous solution. As opposed to previous theoretical works, where analytic solutions ...
Influence of double excitation AC/DC in the reactive power demand of 3-phase transformers
(IEEE, 1999-12-01)
In this work it is discussed the performance of the reactive power demand in three-leg transformer core and three-phase transformer bank, under different conditions of AC/DC double excitation. In order to analyse the ...
Estudo de fluxo de potência harmônico em sistemas de distribuição de energia elétrica
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2011-11-24)
The presence of devices that use power electronics within their operating scheme has increased significantly in recent years. However, the use of such devices directly affects the quality of electric power with respect to ...
