Accurate and fast models of the equivalent circuit (EC) elements gapped multiwinding inductors are essential for design galvanically isolated converters, such as Flyback LLC converters. Typically, EC acquired from measurements or time-consuming FEM simulations, both which disadvantageous optimizing magnetic device. This paper proposes a device that exclusively uses impedance matrix elements, i....
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
We address the objective of the generation of finite magnetic flux out of unbiased thermal current fluctuations in a collection of identical mesoscopic cylinders which are coupled via mutual inductances. The influence of thermal Nyquist fluctuations are described in terms of a set of Langevin equations or a corresponding Fokker–Planck equation, respectively. In the limit of infinitely many cons...
In this paper, the capacitance and inductance of a four-line transmission structure is characterized. The procedure used was developed by Ymeri et al for general analysis of multilayer multiconductor interconnects for specific applications in microelectronics. The characterization is based on the determination of the quasi-static electric scalar potential in the structure making up the four-lin...
abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...
Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...
We give a basic and self-contained introduction to the mathematical description of electrical circuits which contain resistances, capacitances, inductances, voltage and current sources. Methods for the modeling of circuits by differentialalgebraic equations are presented. The second part of this paper is devoted to an analysis of these equations.
this thesis attempts to study the representations of the third-world intellectuals in three fictional works by the british-educated trinidadian nobel-winner v. s. naipaul: the mimic men, a bend in the river, and magic seeds. the first one recounts the story of ralph singh’s sense of alienation, his experiences as a colonial politician, and his struggle to give order to his disorderly world thro...
This paper has been proposed to simulate the transient model of 3-Ф cage rotor induction motor based on winding function approach (WFA). According this method is assumed be consist an electrical circuits both stator and rotor. The magneto motive forces (MMF) that have generated by these play a role for coupling them together. Then mutual self-inductances will easily computed using WFA. Two type...
