The high active and reactive power level demanded by the distribution systems, the growth of consuming centers, and the long lines of the distribution systems result in voltage variations in the busses compromising the ...

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 ...

The purpose of this work is to study voltage control and energy balance of a split DC bus topology within a power electronics equipment connected to the AC mains, such as UPS systems, wind power generators, active filters ...

The Brazilian financial sector net profit amounted to R$22.2 billions in the first semester of 2006. In the previous year this sector invested around R$4.6 billions in Information Technology (IT). Investing in IT is a ...

In this paper it is presented the analysis of an electric power distribution branch containing a photovoltaic system, considering the generation and propagation of harmonic distortion. The obtained results refer to an ...
