Usage of digital controllers in power electronics has been increasing rapidly in recent years. This paper pro-poses the usage of elemental real-time models to evaluate the system behavior and controller performance. An example of a grid-connected inverter (GCI) is selected for validating the performance of the real-time simulation. The system is implemented using the TMS320F28379D development platform under the C2000 real-time micro controller family produced by Texas Instruments (TI). Alongside, an experimental setup is also developed. This work aims to present a way of low-cost experi-mentation that is simple and fast, thus drastically reducing the lead time for development. The real-time simulation data using the digital signal processor (DSP) and MATLAB simulation data are verified with experimental data. It is observed that both MATLAB simulation and real-time simulation using DSP are showing identical results.

This article suggests a vehicle-to-grid (V2G) paradigm based on virtual inertia control for improving Power System Frequency Regulation Services (FRS). As modern grids have far less inertia than prior, thus maintaining reserved power (such as batteries) to mitigate grid frequency fluctuations would entail a very quick and responsive regulatory operation. Although battery energy storage systems are quite expensive, it is advocated that regulated loads such as Electric Vehicles (EVs) may be integrated into modern low-inertia power grids to lessen the required competence of energy storage technologies. Additionally, the impact of intentionally produced delays on control signals in a Hybrid Power System (HPS) is investigated. It demonstrates a straightforward yet effective tactic known as the random delay attack. An adversary causes random delays on a succession of control signals in this attack, causing the nation of the core part to rapidly diverge. As a consequence, an optimal Linear Active Disturbance Rejection Control (LADRC) is employed for frequency regulation in an interconnected restructured HPS employing V2G technology. The controller's gain coefficients are optimized using a modified Quasi-Opposition based Harris Hawks Optimization (QOHHO) strategy. Furthermore, the significant findings of the investigated system validate the presented frequency stabilization scheme.

This paper proposes a new Data Mining Educational Model for knowledge extraction with a minimum presence of data scientists, a scarce and determinant human resource for the application of machine learning in Data Mining. The model allows generating data sets semi-automatically, obtaining an optimized algorithm through automatic machine learning (AutoML) and explaining the results with interpretable machine learning (IML). It is applied in the field of University Education and implements a process with three general stages (Data Analysis and Integration, Data Modeling and Results Evaluation) and is validated by means of a friendly prototype to non-expert users with data obtained from an Argentine Public University. With this proposal we aim to allow universities to draw conclusions on complex problems, requiring a minimum number of data science experts and providing a framework for both end users and legal entities to be informed of the results generated.

The Totem-Pole Power Factor Correction (TP-PFC) boost converter is gaining popularity due to its bridgeless topology for rectification purpose. The performance of such converter is affected by numerous factors as reported in the literature. In this work, a new control strategy for the improved performance of the TP-PFC boost converter is proposed with a focus on the following issues. The occurrence of current spike at the zero-crossing of input current is eliminated by introducing a dead-zone. The mixed conduction mode operation of the TP-PFC is avoided at light load conditions using a variable switching frequency scheme, which also improves the THD. Further, the response of the slow DC voltage control loop affects the dynamic response of the converter. The occurrence of a transient condition is detected in this work, and the voltage controller parameters are modified to speed up the voltage response. Thus, a unified controller combining all the above aspects has been developed, and the working of the proposed control strategy is verified through extensive simulation. The improved performance is also validated against that of the conventional control strategy.

It has become increasingly important to have decentralized devices whitelisted, and distributed self-contained trust management systems when the number of Internet of Things (IoT) assets continues to grow exponentially. The reliance of vendors on devices is increasing without much focus being placed on an open platform and interoperable software architecture. Consequently, enormous amounts of similar IoT devices are injected into systems that typically require massive maintenance and generate large amounts of electrical waste without much consideration for reusability and interoperability. This research paper sufficiently established a novel software architecture and practical solution to manage IoT device interoperability by properly addressing essential core self-managed, whitelisted, and distributed trust management processes.

This research introduces a coupled inductor-based high gain non-isolated DC-DC converter for DC microgrid systems. A coupled inductor and a voltage multiplier circuit are used to provide high gain at a low duty ratio. The main side interleaving lowers the source current ripple. An active clamp auxiliary resonant circuit was included in the converter's primary switches for soft switching. To reduce switching losses, Zero Voltage Switching (ZVS) turn-ON and Zero Current Switching (ZCS) turn-OFF are achieved. The voltage quadrupler circuit for the proposed converter has ZCS turn-OFF on all of the diodes. The voltage stress on all MOSFETs and diodes has been significantly reduced, further reducing loss during switch conduction and increasing the converter's efficiency. This proposed theoretical concept is validated through simulation at 200kHz, which converts 24 $V$ to 400 $V$.

In this work, we have discussed issues with Microsoft's state-of-the-art Speech-to-Text (STT) system. Two key issues have been identified: recognition of Hindi words starting with the fricative phoneme (/ha/) and recognition power of the system with background noise. The solution for correctly identifying the unrecognized Hindi fricative phoneme is by training the Wav2Vec2.0 model on the OpenSLR Hindi dataset. The evaluation of the proposed model is given by the performance metric Char-acter Error Rate (CER). To test the performance of the proposed model, 20 fricative words in both clean and noisy conditions are fed to the trained model. The second issue of handling noisy speech samples is resolved using an amplitude-based automatic noise detection method. The results achieved from the proposed model are observed to be better than the state-of-the-art STT model when trained with and without the language model in terms of CER in clean conditions.

Mixed Reality (MR) collaborative interface allows remote collaboration between an HMD (Head Mounted Display) user in Virtual Reality (VR) and a non-HMD user in Augmented Reality (AR). Both users to have a meeting with each other despite the distance between one another. It enables users to interact in a virtual environment that can replace the traditional way of physical meeting by using appropriate collaborative tools. However, the problem arises when the user is far apart from each other and needs an effective way or tools to collaborate. This paper discusses about a collaborative tool and proposed a prototype called MR-Meet as a collaborative MR interface. MR-Meet has been designed with a tool that can aid both users from different settings to work together. It provides the designing stage to actualize MR collaborative interface with two basic tools such as sticky notes and a whiteboard to help distant people between HMD and handheld users from different locations can be available in one shared environment. To study the user's behavior and experience when they perform collaborative tasks using the two basic collaborative tools. This paper aims to invoke the collaborative tools in MR-Meet meeting space. It describes the users from two different settings, VR user wears HMD and AR user wears handheld device. The methodology describes the interaction of HMD by using a ray pointer while Non-HMD was using a handheld device to utilize its touch-based interaction.

In this article, a three-phase non-adaptive pre-filtered quasi-type-I (QTI) phase-locked loop (PLL) approach is proposed for fast detection of fundamental positive sequence components. For this purpose, a non-adaptive pre-filtering architecture that relies on Lyapunov estimation theory is investigated. It is noted that the Lyapunov's principle-based QTI-PLLs are sensitive to the presence of fundamental negative sequence (FNS), harmonics, and DC-offset components. Thus, it requires additional efforts to resolve the aforementioned issues. Since the internal state-variable feed-backs in the Lyapunov's demodulation approach leads to poor dynamic performance, an improved immunity against DC-offset, harmonics and the FNS are achieved by avoiding state-feedback paths. Consequently, the demodulated error signals in the dq-frame can further reduce the number of state variables and efficiently reject the FNS components. Finally, the numerical results demonstrate the efficacy of the proposed method with respect to an enhanced QTI-PLL approach.
