Direct current

Dipole-dipole array has wide using in resistivity/I.P. surveys because of the low E.M. coupling between the current and potential circuits. The arrangement of the electrodes is shown in Figure( )., Electrodes c1 and c2 are separated by a distance (a), and electrodes p1 and p2 are separated by a distance (b). the distance between the potential electrodes pair c1-c2 is the same as the distance between the potential electrodes pair P1-P2 and the distance between the centers of the respective…

 Novel 3-Phase Single stage boost inverter: Analysis, Design and Experimentation M K Pathak, Member, Dogga Raveendhra and Aravind Panda Abstract— this paper introduces a novel type of 3-phase single stage dc-ac converter, which is controlled by sliding mode control, offers intrinsic step up abilities. Proposed inverter is designed with lesser number of solid state semiconductor switches and small passive elements. Sliding mode controller (robust controller) is designed to control this power…

Winders, Jr In a Y-Y transformer the zero-sequence magnetizing currents produced by the odd harmonics all meet neutral point producing the current that goes through the neutral going back to the voltage supply. It also stops any distortion in the secondary phase voltages as the magnetic flux in the core of the transformer has a sinusoidal waveform and since…

In test system-II, primarily a two area multi source power system is considered with three GENCOs and two DISCOs in each area is shown in Fig. 8. The control area 1 and control area 2 comprises of reheat thermal, hydro and gas power system with the inclusion of non-linearities such as boiler dynamics, time delay (TD), governor dead band (GDB) and generation rate constraint (GRC). Boiler dynamics configuration is incorporated in thermal plants to generate steam under pressure. Changes in the…

3.3.3 Selection of Die Angles The split die was designed for the ease of assembly for fabrication. AISI 52100 steel was selected as the material for the die fabrication. The entry part of the die is 12 mm and has 120 mm length. The profile of the die is also shown in the solid works software. The angle of the die is 90 is maintained, the slope radius is 20 mm. the Figure.3.1 & Figure. 3.2. illustrate the split die design and solid works model of the split die. Figure. 3.1 : Split die…

children with CP. Although this approach is becoming more prominent, more research studies need to be done before it can be used as an approved treatment for children with CP or other neurological disparities. TMS, is similar to TDCS, but instead of a direct pulse it uses a figure-eight electrical coil on the head to make an electromagnetic field that can control cortical excitability and make permanent changes to the brain function (Ramezani et al.). TMS is used in treating ADHD, ASD,…

alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the current only…

CHAPTER1 INTRODUCTION TO ZVT 1.1 What is ZVT? Zero voltage switching can best be defined as conventional square wave power conversion during the switch’s on-time with “resonant” switching transitions. For the most part, it can be considered as square wave power utilizing a constant off-time control which varies the conversion frequency, or on-time to maintain regulation of the output voltage. For a given unit of time, this method is similar to fixed frequency conversion which uses an adjustable…

we will discuss tomorrow is my research topic and datasets. To make sure all the important points are covered during our meeting I wrote them down for you. I would like to talk with you about the current state of my research. I hope that I can have your support to move forward and deepen the current study. Here are some of my reasons: 1. The reason that I pursuing my Ph.D study is that I am greatly interested in Education, and want to find solutions to build a better educational…
