This year, we introduced the concept of infra soft topology as a new generalization topology. To complete our analysis this space, devote paper to presenting concepts connected and locally spaces. We provide some descriptions for connectedness elucidate that there is no relationship between an topological space its parametric spaces with respect property connectedness. discuss behaviors under h...

let g = (v,e) be a locally finite graph, i.e. a graph in which every vertex has finitely many adjacent vertices. in this paper, we associate a topology to g, called graphic topology of g and we show that it is an alexandroff topology, i.e. a topology in which intersec- tion of every family of open sets is open. then we investigate some properties of this topology. our motivation is to give an e...

A soft-switched inverter is derived from the passively clamped quasi-resonant link circuit with three different clamps: coupled inductor, diode clamp and coupled inductor and capacitor. The proposed soft-switching inverter is formed from the traditional pulse-width modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft switching is achieved through applying...

Dynamic response of a converter plays an important role in many applications which change load in a rapid manner, especially in PoL(Point of load)applicat ions. Here a new method for improving the dynamic response of a converter is presented. Here separate control schemes are implemented during steady state as well as transient load conditions. A three level buck converter topology with fast tr...

This letter presents a novel topology for a buck dc– dc converter with soft-switching capability, which operates under a zero-current-switching condition at turn on and a zero-voltage switching condition at turn off. In order to realize soft switching, based on a basic buck converter, the proposed converter added a small inductor, a diode, and an inductor coupled with the main inductor. Because...

One of the considerable topics in soft setting is study topology which has enticed attention many researchers. To contribute to this scope, we devote work investigate two classes separation axioms with respect distinct ordinary elements through one generalizations called infrasoft topology. We first formulate concepts infra- t <...

We analyze the charmless two-body B → V P decays in the soft-collinear-effective-theory (SCET), where V (P ) denotes a light vector (pseudoscalar) meson. Using the current experimental data, we find two solutions in χ fit for the 16 non-perturbative inputs responsible for the 87 B → PP and B → V P decay channels in SU(3) symmetry. Chirally enhanced penguins can only change several charming peng...

modeling and simulation of processing plants are widely used in industry. construction of a mathematical model for a plant is a time-consuming and error-prone task. in light of extensive advancements in computer science (both hardware and software), computers are becoming a necessary instrument in industrial activities. many software tools for modeling, simulation and optimization of processing...

This paper presents a forward converter topology that employs a small resonant auxiliary circuit. The advantages of the proposed topology include soft switching in both the main and auxiliary switches, recovery of the leakage inductance energy, simplified power transformer achieving self-reset without using the conventional reset winding, simple gate drive and control circuit, etc. Steady-state...
