Influence of double excitation AC/DC in the reactive power demand of 3-phase transformers
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 ...
Instantaneous complex power applied to three-phase machines
The theory presented in this paper was primarily developed to give a physical interpretation for the instantaneous power flow on a three-phase induction machine, without a neutral conductor, on any operational state and ...
Non-linear energy harvesting system efficiency comparison from periodic to non-ideal excitation
Dynamics of a non-linear energy harvesting is affected by excitation source and to explore efficiency it is necessary to understand which region offers more energy and the influence of a forced periodic vibration related ...

Excited State Absorption of Doped and Undoped Polyanyline
(TAYLOR & FRANCIS LTD, 2010)
Polyaniline is a conducting polymer with appealing electrical and optical properties, arising from the -conjugation along the polymer backbone. The understanding of its excited state absorption is of prime importance for ...
A Short Note on a Nonlinear System vibrations under Two Non-Ideal Excitations
This paper describes a nonlinear phenomenon in the dynamical behavior of a nonlinear system under two non-ideal excitations: the self-synchronization of unbalanced direct current motors. The considered model is taken as a ...
Simple Excitation Model for Coaxial Driven Monopole Antennas
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
A new excitation model for the numerical solution of field integral equation (EFIE) applied to arbitrarily shaped monopole antennas fed by coaxial lines is presented. This model yields a stable solution for the input ...
Electric Field Effects in the Excitation of Cold Rydberg-Atom Pairs
(AMER PHYSICAL SOC, 2009)
In this work, we study the role of the ac Stark effects on the excitation of nS(1/2) cold Rydberg atoms produced in a rubidium magneto-optical trap. We have observed an atomic population in the nP(3/2) state after excitation ...
