A novel single-phase ZCS-PWM high power factor boost rectifier
(Institute of Electrical and Electronics Engineers (IEEE), 1997-01-01)
This paper presents a novel single-phase high power factor PWM boost rectifier, featuring soft commutation of the active switches at zero-current (ZCS). It incorporates the most desirable properties of the conventional PWM ...
Harmonic propagation analysis in electric energy distribution systems
(2011-12-01)
An important alteration of the equivalent loads profile has been observed in the electrical energy distribution systems, for the last years. Such fact is due to the significant increment of the electronic processors of ...
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 ...
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 ...
Investigating effects of neutral wire and grounding in distribution systems with faults
(2004-12-01)
In some applications like fault analysis, fault location, power quality studies, safety analysis, loss analysis, etc., knowing the neutral wire and ground currents and voltages could be of particular interest. In order to ...
Determination and statistical treatment of short-circuit currents for faults on the lines of networks of 440 kV CESP system
(1995-12-01)
The distribution of short-circuit current is investigated by means of two methods, one direct and the other analytic; both methods consider uniform probability distribution of line faults. In the direct method, the procedure ...
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 ...
An MILP model for the plug-in electric vehicle charging coordination problem in electrical distribution systems
(Ieee, 2014-01-01)
A new mixed-integer linear programming (MILP) model is proposed to represent the plug-in electric vehicles (PEVs) charging coordination problem in electrical distribution systems. The proposed model defines the optimal ...
