In an era of rapid technological innovation, this article provides a comprehensive examination of Gallium Nitride (GaN) Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs). The background section highlights the emergence and application of GaN MOSFETs and their significant advantages over silicon-based and Silicon Carbide (SiC) MOSFETs, such as smaller size, faster switching speed, less heat generation, and optimum operation at high temperatures, indicating that GaN MOSFETs are leading us into a more advanced, digitized future. The article delves into the basic theory of GaN MOSFETs, detailing their unique structure and properties that demonstrate massive potential and practicality in real-world applications such as electric vehicles and 5G technology. The conclusion emphasizes that GaN MOSFETs have already shown their importance in a wider range of industrial sectors and are set to revolutionize various industries, thereby driving overall progress. With diversified applications and broad prospects, the impact and value of GaN MOSFETs have gone beyond single-component applications, and their societal significance is undergoing profound changes. © 2023 ACM.

Bounded Output Feedback Control of Planar systems with Unknown Nonlinear Structures and Application to Output Consensus

引用

IEEE Control systems Letters 2023年 7卷 3379-3384页

作者： Chen, Chih-Chiang He, Shuaipeng Qian, Chunjiang National Cheng Kung University Department of Systems and Naval Mechatronic Engineering Tainan70101 Taiwan University of Texas at San Antonio Department of Electrical and Computer Engineering San AntonioTX78249 United States

This letter addresses the problem of output feedback stabilization for a class of uncertain planar systems with unknown nonlinear structures. The underlying philosophy behind the proposed approach is primarily to revamp/advance the classical lead compensator with an arctangent function-based mechanism that assures bounded control magnitudes, leading to a new design methodology not only conquering the obstruction in constructing state observers but also directing the design of a bounded output feedback stabilizer. Inheriting and leveraging the stability-increasing capability offered by lead compensators, the resultant controller is capable of dealing with systems even suffering from unknown nonlinear structures and measurements concurrently. The strategy presented is further expanded to formulate a bounded output feedback output consensus protocol for uncertain planar two-agent systems with unknown nonlinear heterogeneous dynamics. © 2017 IEEE.

Preceding vehicle identification is crucial for establishing cooperative platooning. This paper presents the development of a prototype preceding vehicle identification system (PVIS) and its field evaluation for the assessment of commercial viability. We designed and assembled a prototype consisting of a processing unit (Jetson Nano board), a communication device (Wi-Fi dongle), a GPS unit, and a distance measurement sensor (Terabee sensor). The Jetson Nano integrates the SparkFun GPS-RTK-SMA unit, the Terabee time-of-flight sensor, and the Wi-Fi dongle. The PVIS prototype in the ego vehicle measures the distance to its preceding vehicle and receives the GPS data from potential preceding vehicles with the PVIS prototypes. With these, the PVIS in the ego vehicle determines the connectivity of the preceding vehicle. The field evaluation results showed that the prototype PVIS works as designed, and each successful identification takes about 5.3 seconds. However, it was found that the Terabee (time of flight) sensor, at times, did not properly measure distances, likely due to an angle issue caused by the roadway surface and vibration of the vehicle. We discussed how to overcome the challenges identified and enhance the prototype for successful commercialization. Copyright © 2024 by SCITEPRESS - Science and Technology Publications, Lda.

Market-Based Environmental Policies in the Power Sector: State of the Art and Future Research Needs

引用

Current Sustainable/Renewable Energy Reports 2023年第3期10卷 59-74页

作者： Siddiqui, Afzal S. Tanaka, Makoto Chen, Yihsu Department of Computer and Systems Sciences Stockholm University Kista Sweden Department of Mathematics and Systems Analysis Aalto University Espoo Finland National Graduate Institute for Policy Studies Tokyo Japan Department of Electrical and Computer Engineering and Environmental Studies Department University of California Santa CruzCA United States

Purpose of Review: So-called Green New Deals aim to decarbonise the power sector via market-based instruments. Consequently, engineering-economic models for analysing the sustainable-energy transition have proliferated. This review categorises existing approaches and identifies areas for extending the state of the art. Recent Findings: We cluster the extant literature into two groups: engineering/operational research (M1) and environmental economics (M2). While M1 focuses on the power sector’s technical and spatio-temporal aspects, M2’s emphasis is on incentives and externalities. Depending on the nature of the research question, either perspective (or both) may be suitable. Summary: Since the envisaged electrification of the wider economy implies tighter coupling between formerly distinct sectors, e.g., power and heat, both M1 and M2 will have to adapt to the new paradigm in terms of methodology and application areas. Here, eliciting coordinating mechanisms, enhancing algorithms for solving hierarchical models, soft linking bottom-up and top-down models, and crafting robust environmental policy in face of uncertainty over externalities are some of the vistas for future research. © 2023, The Author(s).

Smartphones as a means of communication are not only used to send and receive messages and make phone calls. Today's smartphones are also intended to store personal data and sensitive information hence it is vulnerable to be illegally accessed by others. Fingerprint as a biometric lock screen for smartphones can be trusted to ensure the security and privacy of smartphone users. A fingerprint is closely related to a user's identity. When using fingerprints, users provide their personal biometric pattern, unknowingly giving their privacy and making them vulnerable to unauthorized use of their biometric pattern. This study is designed to reveal the factors that influence users when using fingerprints as a smartphone lock, using eight variables adapted from previous research. The data analysis used is Partial Least Squares (PLS) analysis. The results of this study suggest that trust, attitudes, and perceived risk are the factors that influence users when using their fingerprint as a smartphone lock. © 2023 The Authors.

The Free Space Optics (FSO) is a high-speed connectivity system that has the same advantages of speed and bandwidth as that of optic fiber. In comparison to optic fiber, FSO is the preferred choice when it comes to cost and deployment period. However, one of the main challenges with FSO is the changing weather conditions that affect the signal since the transmitted signal is radiated through the atmosphere. This investigation focuses on examining the variables that influence the reduction of visibility at different wavelengths: 750nm, 780nm, 850nm, and 1550nm. The locations of interest concerning visibility and rain data are Pretoria, Upington, Bloemfontein, and Cape Town in the Republic of South Africa. Results indicate that fog attenuates the signal more when compared to rain. Furthermore, signals transmitted at 1550nm will attenuate the signal less when compared to the other wavelengths of interest. © 2024 IEEE.

A single-stage single-phase dual active bridge (DAB) based solid-state transformer (SST) offers various advantages over its multi-stage counterparts, including higher efficiency and reliability due to fewer components and the absence of bulky electrolytic capacitors. However, the lack of a DC link limits its reactive power transfer capability from the supply to the load, a capability even conventional transformers possess. To address this, external compensation elements are required across the load terminals to meet the desired reactive power, diminishing its primary advantage. This paper introduces a technique for a single phase AC-AC DAB-based SST to enhance the transformer's reactive power transfer capacity. It also presents a detailed analysis of the zero voltage switching range of the converter bridges under various operating conditions while supplying reactive power. The proposed schemes and analysis are further validated by experimental results on a 120/164 Vrms and 450 VA hardware prototype, demonstrating a correlation with the experimental results and highlighting the practical benefits of the proposed scheme. © 2024 IEEE.
