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) ...
Integrated planning of electric power distribution networks
(2009-12-01)
In this work, a heuristic model for integrated planning of primary distribution network and secondary distribution circuits is proposed. A Tabu Search (TS) algorithm is employed to solve the planning of primary distribution ...
Reference generator for voltage controlled power conditioners
(2011-12-28)
Voltage reference generation is an important issue on electronic power conditioners or voltage compensators connected to the electric grid. Several equipments, such as Dynamic Voltage Restorers (DVR), Uninterruptable Power ...
Analysis and design of constant-frequency peak-current-controlled high-power-factor boost rectifier with slope compensation
(1996-01-01)
This paper presents the analysis and the design of a peak-current-controlled high-power-factor boost rectifier, with slope compensation, operating at constant frequency. The input current shaping is achieved, with continuous ...
A new three-phase low THD power supply with high-frequency isolation and 60V/200A regulated DC output
(2001-10-22)
This work proposes a new isolated high power factor 12kW power supply based on an 18-pulse transformer arrangement. Three full-bridge converters are used for isolation and to balance the DC-link currents, without current ...
Three-phase four-wire circuits interpretation by means of different power theories
(2010-08-23)
In order to contribute to the discussion of defining a generalized power theory, valid for unbalanced and non linear circuits, this paper discusses the relationship and discrepancies among four modern power theories. ...
Proposal of a dedicated telemetry device for real-time and remote measurements
(2011-09-05)
This work aims to demonstrate an application of telemetry for monitoring process variables. The authors developed the prototype of a dedicated device capable of multiplexing, encoding and transmitting real-time data signals ...
Design of a CMOS voltage reference using current-model approach
(2011-05-20)
A voltage reference with low sensibility to temperature and power-supply that can generate flexible reference values (from milivolts to several volts) is proposed. Designed for AMS 0.35μm CMOS process, the circuit provides ...
Bandgap voltage reference with low susceptibility to electromagnetic interference (EMI)
(2011-10-25)
In this paper, the susceptibility of a current-mode bandgap voltage reference to electromagnetic interference (EMI) superimposed to the power supply is investigated by simulation. Designed for AMS 0.35 CMOS process, the ...
Optimal allocation of distributed generators providing reactive power support ancillary service
(2011-10-05)
Problems as voltage increase at the end of a feeder, demand supply unbalance in a fault condition, power quality decline, increase of power losses, and reduction of reliability levels may occur if Distributed Generators ...
