Prediction of voltage over electrodes' filaments of fluorescent lamps during dimming operation
(2005-12-01)
This paper presents an investigation concerning the use of fundamental approximation analysis and a new lamp model for the prediction of the voltage over electrodes' filaments during dimming operation. The lamp model ...
Dimmable electronic ballast with high power-factor SEPIC preregulator, for multiple tubular fluorescent lamps
(2004-11-29)
An electronic ballast for multiple tubular fluorescent lamps is presented in this paper. The proposed structure features high power-factor, dimming capability, and soft-switching to the semiconductor devices operated in ...
New family of zero-current-switching PWM converter
(1999-12-01)
A new family of dc-to-dc pulse-width-modulated (PWM) converters is presented. These converters feature soft-commutation at zero-current (ZC) in the active switches. The new ZCS-PWM Boost and new ZCS-PWM Zeta converters, ...
Electrical properties of individual and small ensembles of InAs/InP nanostructures
(2006-05-01)
We investigate electrical properties of InAs/InP semiconductor nanostructures by conductive atomic force microscopy (C-AFM) and current measurements at low temperatures in processed devices. Different conductances and ...

A low-voltage low-sensitivity sinusoidal VCO for DPLL realizations
(2004-09-07)
A quasi-sinusoidal linearly tunable OTA-C VCO built with triode-region transconductors is presented. Oscillation upon power-on is ensured by RHP poles associated with gate-drain capacitances of OTA input devices. Since the ...
An active/reactive predispatch model incorporating ramp rate constraints solved by dual decomposition/lagrangian relaxation
(2004-12-01)
The Predispatch model (PD) calculates a short-term generation policy for power systems. In this work a PD model is proposed that improves two modeling aspects generally neglected in the literature: voltage/reactive power ...
