Miniaturization of Buck-Boost DC-DC Converter with Fast P Control
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015-11-22)
This paper presents a consideration about miniaturization of buck-boost dc-dc converter with the fast P control. From frequency characteristics, it is identified that fast P control method is useful to suppression of output ...
Modelling Marshall Design Test Results of Polypropylene Modified Asphalt by Genetic Programming Techniques
(BUDAPEST UNIV TECHNOLOGY ECONOMICS, PERIODICA POLYTECHNICA CIVIL ENGINEERING, BUDAPEST, 1521, HUNGARY, 2015-02-16)
Determining Marshall design test results is time consuming. If the researchers can obtain stability and flow values by mechanical testing, rest of the calculations will just be mathematical manipulations. Marshall stability ...
Performance Characteristic of Digital Peak Current Mode Control Switching Power Supply
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015-09-08)
The purpose of this paper is to discuss performance characteristic of digital peak current mode control switching power supply. The proposed method can capture the peak current value in real time by using the voltage ...
A Consideration of Loss Component in Model Control DC-DC Converter
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015-11-22)
Recently, the energy saving is required. It is necessary for the energy saving to operate the electric device in the sleep mode. Therefore, the output voltage rises abnormally because the dc-dc converter is required the ...
Design of Power Control Unit for Heat Recovery Device Used in Renewable Energy System
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015-11-22)
Heat recovery devices are used for saving energy especially for the renewable energy systems because of effective usage of electrical energy while providing air conditioning in spaces which needs fresh air. These devices ...
A New Quick Response Digital Control DC-DC Converter with Dynamic Unstable Gain
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 2015-11-22)
In this paper, we present a new quick response digital control dc-dc converter based on a dynamic unstable gain to improve transient response. In the proposed method, the proportional gain is set to the small value in the ...
Attention Competition with Advertisement
(Amer Physical Soc, One Physics Ellipse, College Pk, Md 20740-3844 Usa, 2014-09-03)
In the new digital age, information is available in large quantities. Since information consumes primarily the attention of its recipients, the scarcity of attention is becoming the main limiting factor. In this study, we ...
Effect of infill wall and wall openings on the fundamental period of RC buildings
(WIT PRESS, ASHURST LODGE, SOUTHAMPTON SO40 7AA, ASHURST, İNGİLTER, 2013-07-08)
The effect of infill walls to stiffness of the structures has been known for a long
time and this effect has taken many of the earthquake regulations with empirical
relationships and equations into account. However, in ...
PMSM Drive Fed by Sliding Mode Controlled PFC Boost Converter
(SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2014-04-05)
In this study, a vector controlled permanent magnet synchronous motor (PMSM) drive fed by a two-level inverter which is connected to a boost converter with sliding mode control (SMC) for power factor correction (PFC) is ...
Domains of Dynamic Instability of FGM Conical Shells Under Time Dependent Periodic Loads
(Springer Nature, 2016-02)
On the basis of the dynamic version of linear Donnell type equations and with deformations before instability taken into account, the dynamic instability of simply supported, functionally graded (FG) truncated conical ...
