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.

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.

A promising solution to meet the growing charging demand of electric vehicles (EVs), is to incorporate renewable energy resources based charging stations. Thus, a cascaded IIR filter is utilized here for the EV charging system based on PV array, fuel cell stack and wind turbine sources. The satisfactory operation during the grid availability/unavailability is attained through the current and voltage based control mechanisms, along with the seamless transition capability via switching (STS-1/0) of the static transfer switches. Therefore, for adequate operation during modes associated with grid existence and non-existence, a cascaded IIR filter is utilized. Moreover, with respect to various weak grid conditions, adequate system performance is observed.

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.

Wireless systems and Internet of Things (IoT) sensing applications need Low Noise Amplifiers (LNA). However, a simple design is desirable for wearable IoT applications. In this direction, a single-stage LNA having considerable gain, stability, and noise figure (NF) for wearable IoT applications have been designed. An analysis of gain, noise factor, and stability for various values of gate voltage is performed to determine the utility and performance. The transistor used here is a Low Noise Gallium Arsenide FET and lumped components are used for matching at input and output side. It is found that the proposed LNA has 15.689 dB forward gain, a bandwidth of 1600 MHz and 0.672 dB Noise Figure at frequency 2.4 GHz that can be used for sensors operating in LS bands of frequencies. The LNA has been designed with fewer components in order to make it suitable for wearable IoT.

This paper proposes a control technique for a Dual active bridge (DAB) based Solid State transformer (SST). An input folder circuit, DAB DC/DC converter, and output unfolder circuit comprise the proposed converter topology. This article analyzes soft-switching conditions and transformer current stress for DAB based SST topology at different load conditions and suggests an optimal control path. The proposed control path is created by choosing the ideal set of control variables, thus extending the ZVS range and lowering current stress. The traditional Phase shift modulation (PSM) method is compared with the proposed control strategy, and the results show improved performance. To verify the effectiveness of the suggested control technique, experimental findings from a scaled-down prototype are provided.

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.

Increasing the penetration of renewable energy sources into an existing power system reduces the system's inertia, which can result in stability issues. Consequently, monitoring the different oscillatory modes resulting from an inverter-based generation's integration to a grid is of great concern. Most renewable energy sources operate based on maximum power point tracking (MPPT), because of economic reasons, since they are strongly dependent on weather conditions, which are intermittent and fluctuate. Battery energy storage systems (BESS) can provide a solution to the stochastic nature of renewable energy sources, because of a BESS's capability to store energy, support bidirectional energy exchange, provide geographical independence, and support fast output response. In this paper, a BESS along with a photovoltaic (PV) system are connected to a power grid via grid following and grid forming control architectures to study the oscillatory modes. A subspace identification method is used to identify oscillatory modes and their damping ratios from the measured voltage dynamics are obtained for the test system.

Single-stage AC to AC converter topology based solid-state transformers (SSTs) are being explored nowadays because of the higher efficiency of conversion. This paper presents a novel single-stage AC/AC converter topology for the solid-state transformer (SST), based on the LLC resonant converter. Four-quadrant ac switches are utilized on the primary side of the proposed converter to eliminate the folding bridge requirement and give a direct connection to the ac grid. Load-independent operation can be achieved by operating at the resonant frequency of the converter. Thin-film capacitors are used instead of bulky electrolytic capacitors to reduce the overall system capacitance and achieve high power density. Operating modes and soft-switching conditions are discussed in detail. Hardware prototype is developed to validate the operation of the proposed converter.

The Internet of Things (IoT) becoming popular day by day as it's a vast set of applications. All these applications are based on smart and tiny sensors. In many applications, information sensed by the sensor is useful, if its location is known. Therefore, the sensor node's accurate location is required in the monitoring region for realistic applications. In, a Wireless Sensor Network (WSN), finding the correct location of sensors is a challenging task. To overcome the shortcoming of DV-Hop, in this paper, modified differential evolution-based enhanced DV-Hop (DEEDV-Hop) is proposed. The proposed DEEDV-Hop has three phases, phase one is similar to the original “DV-Hop”, in the second phase, the hopsize of Beacon Nodes (BN) is calculated at Unidentified Node (UN) to reduce the energy consumption and at least three BNs is selected in the nearby vicinity of UN. For hopsize computation, only those BNs are selected which have their mutual hop distance close to the integer value of communication radius (R). Finally, the modified differential evolution (DE) algorithm is used to find the location of UNs. The adjustment factor is added to refine the hopsize. The simulation findings confirm that, when compared to existing localization schemes, our proposed technique enhances Localization Accuracy (LA) and minimizes Localization Error (LE), Localization Error Variance (LEV).
