A piezo transducer translates the applied voltage to a sound wave, demanding a power amplifier as a preprocessor to ensure an interpretable echo. The distinctive characteristic of the problem arises from the fact that such transducers are predominantly capacitive. This paper presents a class-D sonar amplifier designed and built to drive a particular acoustic transducer with a 50 Ω impedance at a resonant frequency of 400 kHz. Because of its high efficiency and compact nature, the class-D has been chosen as the power amplifier topology over its linear counterparts. When triggered with self-oscillating driver IR2086STRPBF, the bridge inverter generates a high-frequency square wave. The proposed parallel IMN enables high voltage gain and restricts the total harmonic distortion (THD). Thus, peak power of 500 W from a low-voltage source of 60–96 Vdc is ensured by employing a boost-type IMN. The simulation and experimental results show that the designed amplifier has reduced power losses when operated in the inductive.

The annual increase in global energy demand is taking place when fossil fuel reserves are finite and are only anticipated to last for a few more decades. Consequently, it is unavoidable to use resources that derive from renewable energy sources. However, technological and economic assessments are required to construct the infrastructure for a renewable energy system that can generate electricity. This study examines the feasibility of producing 5kW of electricity from renewable sources, including solar PV modules, inverters, and the necessary batteries, at various sites around Pakistan. Additionally, data from multiple places are contrasted. System evaluation is done using the SAM (System Advisor Model) tool, and it's designed for a project that will last 25 years. The study concludes that the price of a solar photovoltaic module will be the project's principal limiting issue.

Solar energy is a renewable energy source that is abundantly available in Pakistan. Solar energy is a green energy that contributes to cater the adverse effects of conventional energy sources on environment. A parabolic dish solar cooker is designed to utilize solar heat energy for cooking purposes. Solar cooker comprises mainly of a reflective concentrator and a receiver pot. Greenhouse effect is applied by placing a glass jacket around the receiver pot that aid in rise of receiver temperature and cater for ambient effects on receiver. Performance of the parabolic dish solar cooker is analyzed at two different locations of Pakistan (Islamabad and Multan). The experimental results indicate that solar flux and effective concentration of solar irradiance has major contribution in PDSC performance. Also, it is concluded that time required for attaining high temperature i.e., (90°C) 363.15 K in Multan is 30 minutes less compared to Islamabad due to variable ambient conditions. Similarly, the amount of heat energy stored by water and the heat energy readily available during cooking i.e., cooking power is more in Multan scenario comparing it with Islamabad. From the results obtained it is concluded that PDSC has a great potential to be used as an alternative to conventional cooking methods.

This article presents a techno-economic analysis of single and multi-crystalline silicon solar panel installations for solar irrigation pumping applications in two cities in South Punjab, Pakistan. The study considers various economic parameters, such as net capital cost (NCC), levelized cost of electricity (LCOE), net present value (NPV), and payback period by employing system advisory model (SAM) software. The results indicate that although monocrystalline solar panels have a higher initial cost than polycrystalline panels, they offer higher efficiency, longer lifespan, and lower maintenance costs, resulting in a lower LCOE, higher NPV, and shorter payback period. This study also examines the material science aspect of silicon used in Mono (Single) and Poly (Multi) crystalline solar panels. The impurity and purity levels of silicon in the panels can greatly affect their performance and durability. Monocrystalline panels are made from a single, pure crystal of silicon, while polycrystalline panels are composed of multiple crystals. The study also provides insights into the impurity and purity levels of silicon and their impact on the performance of solar panels. The findings of this study can help decision-makers in choosing the optimal solar panel technology for their energy needs in the region.

Currently, there is a growing interest in the topic of power quality across the entire electric power system. The power system is a complex network of modules with a broad distribution area, designed to meet the demand for electric power. The power system is susceptible to a range of disturbances arising from either dynamic consumer load behavior or faults. The power system necessitates a precise and advanced stability and protection mechanism. Ensuring the safe and reliable operation of the power system is a significant challenge, with voltage stability and fault protection being key areas of concern. The present research study proposes a technique to augment the stability of a grid-connected system that comprises of several generating sources through the utilization of FACTS devices, specifically static synchronous compensator (STATCOM). The technology has been designed to enable the monitoring of supervisory control of devices, while the distribution system offers decision-making tools to enhance system performance. A fault was generated between the time interval of 1-1.04 sec duration, and the simulation waveform was subsequently observed. The present study entails a simulation-based comparison between a power system without a STATCOM devise and one equipped with the STATCOM. The analysis results of the transient voltage stability of HV AC transmission lines utilizing STATCOM.

Generation expansion planning (GEP) is a primary and rigorous exercise in shaping the long-term decisions in terms of capacity expansion, location and technology of the power plants, to be committed for next 25–30 years, based on forecasted electrical demand. It is a non-linear, mixed-integer, stochastic, dynamic and discrete optimization problem. The metaheuristics are deemed the best optimization techniques to answer this multi-dimensional optimization problem with a large number of complicated constraints. In this work, least cost GEP problem is solved using a new optimization technique named as Artificial Hummingbird Algorithm considering the future horizon of 14 years encapsulating power generation additions required to cater for the forecasted peak demand with significant reliability and reduced emissions. A new efficient radix-5 mapping method for the representation of population search agents and power plants selectivity method based on priority enlisting is embedded in AHA framework. AHA has been implemented on standard emission constrained test cases considered in the literature. The proposed GEP framework provides promising results in terms of least cost and computational time with enhanced reliability and reduced emissions in contrast to the approaches presented in the literature.

This study aims to install a solar thermal-powered adsorption chiller and evaluate its performance by integrating a test bench into the system. Adsorption chillers can utilize low-grade heat sources below 80°C to operate efficiently without using refrigerants causing carbon emissions and global warming. The commercially available Adsorption Chiller of 4.79 Tons capacity was installed, with a flat plate collector and a cooling tower for heat dissipation. Results showed that average cooling ranged from 0.9 kW to 5.32 kW, with a maximum coefficient of performance (COP) of 0.32 when inlet temperature was varied from 50°C to 65°C, respectively and the flow rate varied from 0.23kg/s-0.27kg/s for high temperature and 0.23kg/s to 0.25kg/s for low temperature line. This study highlights the potential for adsorption chillers to exploit untapped heat sources and improve energy efficiency while minimizing environmental impact. The results of this study can contribute to the development of more efficient and sustainable cooling systems, which can be used to mitigate climate change and promote sustainable development.

Recently, a considerable growth in energy demand has been observed and predominantly this increased demand in energy is met by the burning of fossil fuels. Renewable forms of energy can offer solutions to issues that have persisted for a long time in the energy sector. Most promising form of renewable energy is solar energy and solar air collectors are an effective technique of utilizing abundant solar energy for heating purposes and lowering the consumption of electrical energy and fossil fuels. This study integrated a flat plate solar air collector with desiccant dehumidification system to regenerate desiccant material. The performance of the proposed FPSAC-assisted rotary desiccant system in terms of outlet temperature, dehumidification effectiveness (DE), moisture removal capacity (MRC) and sensible energy ratio (SER) was evaluated by varying flow rates of process air in the range 33 m3/h, 51 m3/h, and 62 m3/h. The experimental results indicate that an inlet process air flow rate of 33 m3/h provides the maximum DE (0.71) and the maximum percentage increase in air temperature (68.42%) after dehumidification. Furthermore, highest MRC and SER values were found to be to 12.69 kg/h and 1.26 for the highest process air inlet flow rate i.e., 62 m3/h. In short, this study provides information on the potential of a FPSAC to provide regeneration air for continuous desiccant dehumidification.

In short, this study provides information on the potential of a FPSAC to provide regeneration air for continuous desiccant dehumidification.","PeriodicalId":350869,"journal":{"name":"2023 International Conference on Emerging Power Technologies (ICEPT)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114238272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
