Comparative Study and Performance Analysis of Various Fibonacci Pattern of Solar Photovoltaic Tree—An Extensive Review

Abstract: In order to fulfill the world’s energy demand and to reduce greenhouse gas emission, it is requisite to develop energy efficient (%) solution from solar energy to electrical energy. Since, the photovoltaic flat level module has an insufficient collection of solar energy. Inspire of this PV flat module technology has problem of land demands, effectiveness and shortfall of pleasant attractiveness. This paper basically gives overview of newly modified technology-solar photovoltaic tree that can overcome these challenges effectively. Fibonacci form of technique is used in solar photovoltaic trees for maximum energy transform in each direction. This review paper shows analysis of two kinds of solar photovoltaic trees form of on Fibonacci pattern, such as 2/5 and 3/8 phyllotaxis form of solar photovoltaic trees. The performance (o/p power and efficiency (%)) of the classical solar panel, 3/8 and 2/5 phyllo-taxis pattern is studied and analyzed. Solar photovoltaic tree innovation generates good energy transformation since it requires only 1% of land in comparison to classical/classical flat module PV systems. This system also gives power extra than 10% with respect to classical PV system.

Selection of Grippers-A Fuzzy Graph Theoretic Approach

Abstract: the optimum selection of grippers is a complex task as it involves large tangible and intangible attributes and also availability of large options in the market. In this present work, an endeavour has been made to quantify intangible attributes by using fuzzy MADM approach and then overall numerical index has been find out by using Graph Theoretic Approach (GTA) So, that the customer can visually compare different models.

Grid Integration of 3P3W Single-Stage Solar PV System Using Modified Digital Filter Control

Abstract: This paper presents the grid interfaced 3P3W (Three-Phase Three- Wire) solar PV (Photovoltaic) system. The MDF (Modified Digital Filter) control technique is used for fundamental load current extraction and providing the VSC (Voltage Source Converter) switching. The grid interfaced VSC is used to provide active power to the load and surfeit power fed to the grid. Moreover, VSC provides reactive power compensation, harmonic mitigation, and load balancing. Simulated results of the proposed system have shown a good response under steady-state and dynamic-state conditions. The grid current THDs (Total Harmonic Distortion) are well within recommended IEEE-519 limits.

A Systematic Study on Mitigating Parameter Variation in MOSFETs

Abstract: The VLSI design was horse-powered mainly by the elegant and simple MOSFET (Metal Oxide-Semiconductor Field Effect Transistor) which amazingly yielded to the designer’s scaling wishes; Though its operation is governed by umpteen kinds of parameters which depends on the physical dimensions, many process-related aspects as well as the ambient features of the device. The dependence of these parameters on the above-mentioned factors make them vulnerable to variation. Thus, the effect of parameter variations can be summed up as the reduction in wafer yield and hence profit. Over the years, designers were diligently researching and coming up with solutions to combat the menace of parameter variation according to the extent of variation and stringency of requirement. The solution approaches range from not-so-sophisticated marketing techniques such as frequency-binning to the employment of sophisticated techniques such as body biasing to automatically compensate the parameter variations. This paper aims to probe various reasons and impacts of the parameter variations in MOSFETs and to describe some of the techniques to mitigate the parameter variations in a systematic manner.
