Hardware Implementation of BI- Directional Buck Boost Converter for V2g System with Hybrid Energy Storage System
Authors:-Scholar Samyuktha. T, Professor Ganesan.S

Abstract-In modern power system operations, demand side integration is one of the key functions which enables active consumer participation. Electric vehicles (EVs) encourage active participation of consumers for power management. In vehicle to grid integration (V2G), energy storage system (ESS) is connected with the grid through bidirectional converters. The topology for V2G integration consists of ESS, switching bidirectional buck-boost converter, full bridge inverter, and grid. Now-a-days, hybrid energy storage system (HESS) is an attractive solution for EVs. In this work, a topology for V2G with HESS is proposed. This topology comprises of an active HESS in which Li-ion battery is connected to the super capacitor via a bidirectional dc-dc half bridge converter, and full bridge inverter. The fuzzy logic controller using triangular membership functions and hysteresis current controller are proposed for inverters and bi-directional dc-dc converter respectively. The simulation of proposed topology is developed in MATLAB 2021 and the performance is verified. The hardware has been developed which comprises of a bi-directional buck-boost converter (HESS) and converter. The converter plays a crucial role in managing the bi-directional flow of energy between (EV) and the power grid, facilitating both charging and discharging operations. the several critical observations were made. The selected MOSFETs performed reliably under high-speed switching conditions, and the low inductors and capacitors minimized power losses. The tapping transformer provided robust electrical isolation and effective signal transfer, with adjustable voltage taps enhancing MOSFET switching performance. The DSP30F2010 microcontroller, using fuzzy logic control, offered precise and adaptive regulation.

Microplastic Menace: Unraveling the Presence, Sources and Health Impact in Domestic Tap Water
Authors:-Jyoti Punia

Abstract-Microplastics, tiny plastic particles less than five millimetres, are a significant ecological risk. They are found in soil, sediment, and surface water. A study examining microplastic contaminants in tap water in residential areas found three types: cellophane, cellulose, and poly (2, 2, 2-trifluoromethyl vinyl ether). The study highlights the need for effective mitigation measures and provides insights into the health concerns associated with different types and concentrations of microplastics. Ensuring safe and clean water is crucial for public health, making water quality protection essential for managing microplastic pollution.

Cost-Benefit Analysis of Open-Source VS. Commercial Test Automation Frameworks in Large-Scale Enterprise Applications
Authors:-Kodanda Rami Reddy Manukonda

Abstract-The abstract examines, in the context of large-scale enterprise applications, the cost-benefit comparison between commercial and open-source test automation frameworks. It compares the initial and continuing expenses of the two solutions before moving into the financial ramifications. Although open-source frameworks frequently have cheaper upfront costs, the analysis draws attention to potential hidden costs such the requirement for specialized knowledge, longer setup times, and ongoing maintenance. On the other hand, commercial frameworks usually come with hefty licensing costs, but they also provide excellent customer service, seamless integration, and improved capabilities that help hasten the testing procedure. In addition, the assessment takes into account community support, scalability, security, and long-term viability, giving a thorough picture of the effects different frameworks have on total cost of ownership, productivity, and risk management. The results indicate that although open-source solutions might be beneficial for smaller projects or companies with strong internal expertise, commercial frameworks typically offer larger businesses better value because of their dependability, user-friendliness, and extensive support, which eventually results in more predictable outcomes and reduced risk throughout the project lifecycle.
