This paper compares single-stage and dual-stage Improved Linear Sinusoidal Tracer (ILST) based three-phase grid-tied photovoltaic (Pv) systems. These systems facilitate the integration of solar energy into grid while improving the power quality of the distribution network. This design incorporates Maximum Power Point Tracking (MPPT), Pv power injection into the grid, harmonic reduction at the Point of Common Coupling (PCC), and grid current balancing. Both single-stage and dual-stage configurations utilize a three-phase voltage source converter (vSC) controlled by an ILST algorithm. The single-stage and dual-stage systems are modeled and simulated using MATLAB. This ILST control algorithm of grid-tied Pv system helps to maintain Total Harmonic Distortion (THD) of PCC voltages and grid currents within prescribed limits.

optically-controlled high-voltage power devices hold good promise for grid and renewable energy applications by providing superior electromagnetic interference (EMI) immunity and reduced switching delay. This paper proposed a novel optically-controlled gate driver architecture that applies complementary optical signals to two photodiodes (PDs) arranged in a totem-pole configuration. This configuration enables fast switching of power semiconductor devices using minimal optical power, as only low-power driver signals are optically modulated and device main current is not photogenerated. To validate this approach, we employ two InGaAs PDs to drive a 3.3 kv SiC MOSFET, the highest-voltage industrial unipolar device currently available. When each PD is illuminated by 21.7 mW optical power, the SiC MOSFET achieves hard-switching at 1500v/3A, with rise and fall times of 152 ns and 214 ns, respectively. These results set new records for switching voltage, speed, and power capacity-to-optical power ratio in optically-controlled unipolar power switches. This general optical driver design is also applicable to the future development of integrated optics for power electronics in diverse (ultra-) wide-bandgap semiconductors. 1

A comparator is a digital or electronic circuit which is used to compare the given two inputs to give the result (greater than or lesser than or equal). This is widely used to compare the voltages and current in electrical as well as electronic circuits. This project proposed a design of 8-bit comparator which compares 8 bits of two binary data. This 8bit comparator is slightly different from conventional comparators, which can be built with two 4 bit comparators using XNOR gates or by neglecting the logic for greater or lower output;that result in reduction of gates and area. The simulations of the comparator can be done using verilog code in Xilinx tool and analyzing its performance for various inputs in the same way a security password circuit and the cascading circuit are design as a application using proposed 8-Bit comparator. © 2022 IEEE.

With the latest developments in transportation technologies and services, the concept of MaaS has spawned its way, where consumers can purchase access to different modes and services owned and operated by several mobility service providers through a single integrated digital platform. Nonetheless, the MaaS ecosystem and benefits have not been fully understood yet, which varies case by case depending on the communities' behavioral responses. Qatar is known as one of the countries with a highly diverse population where many expatriate workers come from different cultures. This necessitates a comprehensive mobility arrangement given their various travel needs and diaries. To contribute to a comprehensive analysis of MaaS impact while taking into consideration societies' diversities, this paper aims to develop a framework to assist in evaluating and assessing MaaS design alternatives and their impact on different population segments. This study was conducted by utilizing existing literature findings about MaaS assessment supported by a stated preference (SP) survey from a Qatar case study. We found that there are a limited number of key performance indicators (KPIs) to comprehensively evaluate MaaS social impacts and mobility network efficiency. Therefore, as part of the assessment framework, additional KPIs were introduced for comprehensively evaluating MaaS's direct impact on transport networks and broader implications for social equity, economy, and human well-being. MaaS KPIs should consider reporting by age, monthly income, and ethnic socio-demographic factors. This can serve as a useful guide for diverse communities, particularly in Qatar. Furthermore, outputs from the assessment framework can be used as inputs to evaluate impacts on the MaaS provider's profit-making and business prospects. © 2024 Elsevier B.v.. All rights reserved.

The growing demand for high-voltage direct current (HvDC) power supplies in the field of remotely operated vehicles (ROvs) has experienced a significant rise due to developments in underwater exploration and intervention technologies. This study provides an in-depth analysis of the design and assessment of a HvDC power supply system for ROvs. The main goal is to attain a substantial direct current (DC) voltage output of 5000 v, which is crucial for supplying power to ROv activities in deep-sea environments. To achieve this objective, a sophisticated configuration of a 24-pulse rectifier is presented and thoroughly examined. The design process entails a detailed evaluation of component selection and circuit topology to guarantee optimal efficiency and reliability. The 24-pulse rectifier is specifically focused on the benefits it provides, especially in terms of minimising harmonics and enhancing power quality. These factors are crucial for underwater applications, where ensuring a reliable and efficient power supply is of utmost importance. The suggested HvDC power supply is subjected to comprehensive evaluation through simulation studies. The success of the design technique is validated by thoroughly assessing performance parameters like voltage regulation, efficiency, harmonic distortion, and ripple factor. The proposed system demonstrated approximately 99.99% efficiency, with a total harmonic distortion (THD) of 0.045 and voltage and current ripple values of 0.0646% and 10.3911%, respectively.

The article demonstrates the brief fabrication method of the flexible organic thin film transistor (OTFT) developed earlier and its utilization for the development of various basic logic gates (NAND, NOR, AND, NOT, and OR Gates). The compact modeling of the fabricated device and the implementation of the logic gates has been carried out using Silvaco-Techmodeler and Silvaco-Gateway tools, respectively. The device can operate at -2 v supply with good electrical characteristics in terms of -2μ A drain current, ION/IOFF ∼ 103 ' and μp∼ 0.1cm2/v-sec respectively. The Silvaco-Gateway tool implements the logic gates with excellent characteristics, demonstrating logic swing of 1.18 v and a delay of 3.7 ns. The logic gates also possess a good transient characteristic with all four possible logic inputs (00, 01, 10, and 11). The Silvaco-Techmodeler tool models the device with an accuracy of approximately 100%, with a 0.07% and 0.08% error between the experimental and modeled data, respectively. The cost-efficiently fabricated solution-processed transistor in this article can be further utilized in the fields of medical and sensing applications. © 2025 IEEE.
