Novel high-power-factor isolated electronic ballast for multiple tubular fluorescent lamps
(2001-01-01)
This paper presents a novel isolated electronic ballast for multiple fluorescent lamps, featuring high power-factor, and high efficiency. Two stages compose this new electronic ballast, namely, a new voltage step-down ...
An LMI Approach to Full- and Reduced-Order Switched Luenberger Observers for Switched Affine Systems
(2016-12-01)
This work deals with reduced-order Luenberger-like observer design and control for switched affine systems. Formulation of state-dependent and dynamic output-dependent switching laws for those systems was already addressed, ...
A unity power factor multiple isolated outputs switching mode power supply using a single switch
(1991-03-01)
The authors present an offline switching power supply with multiple isolated outputs and unity power factor with the use of only one power processing stage, based on the DC-DC SEPIC (single ended primary inductance converter) ...
A unity power factor multiple isolated outputs switching mode power supply using a single switch
(1991-03-01)
The authors present an offline switching power supply with multiple isolated outputs and unity power factor with the use of only one power processing stage, based on the DC-DC SEPIC (single ended primary inductance converter) ...
Network reconfiguration and loss allocation in a deregulated environment of distribution systems
(2005-12-14)
Low flexibility and reliability in the operation of radial distribution networks make those systems be constructed with extra equipment as sectionalising switches in order to reconfigure the network, so the operation quality ...
A new family of zero-current-switching PWM converters and a novel HPF-ZCS-PWM boost rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 1999-01-01)
A new family of direct current (DC) to DC converters based on a zero current switching pulse width modulated (ZCS-PWM) soft commutation cell is presented. This ZCS-PWM cell is consists of two transistors, two diodes, two ...
Static converter: didactic support software
(1994-01-01)
Teaching a course of special electric loads in a continuing education program to power engineers is a difficult task because they are not familiarized with switching topology circuits. Normally, in a typical program, many ...
