Nowadays, DC microgrids control problems are considered as attracting challenges for the researchers. Thus, a distributed control strategy is presented in this paper for meshed DC microgrids enhancement. The strategy consists of two control layers, a primary control layer and a secondary control layer. The primary controller regulates the terminal voltage of each Distributed Generator Unit (DGU), while the secondary controller takes the responsibility of achieving equal current sharing between DGUs. Two Adaptive PI Controllers (APICs) are proposed for the secondary control layer to enhance the dynamic performance of the system. Validation of the proposed controllers is done under different loading conditions to show the improvement of the current sharing using the adaptive controllers.

High inductance-density with high saturation current on-chip integrated power inductors support achieving high-density integrated power conversion. To guide the design of on-chip planar power inductor, a 3-D physical model in ANSYS®/Maxwell® is developed and utilized in this paper to evaluate the effect of copper winding number of turns on two of the main power inductor performance metrics, namely the inductance value/density and the saturation current. The tradeoff between the inductance value/density and the saturation current as a function of the copper winding number of turns is evaluated using the presented physical model.

Due to their superior merits over Z-source inverters, Split-Source Inverters (SSIs) has been proposed as a potential candidate for high-gain single-stage DC-AC topology. Singlestage DC-AC converters with high gains are particularly useful for interfacing PV modules with AC power grids and loads. In this study, SSI is used to interface PV modules with a singlephase grid. A simple control algorithm based on finite control set model predictive control (FCS-MPC) without needing a pulse-width modulator is presented. In this algorithm, the DClink voltage is adjusted by adjusting the grid current through the linear PI controller. Furthermore, the FCS-MPC is responsible for controlling the grid current and the input current to the SSI. The SSI input current is controlled to track the reference value determined by the MPPT algorithm. The main concept, block diagram and mathematical analysis of the proposed algorithm are presented. The system is simulated using MATLAB/Simulink to validate the proposed control algorithm. According to the simulation results, the proposed control scheme exhibits robust dynamic behaviour. Further, comparisons between analytical, modelled, and simulated responses are presented to verify the proposed algorithm.

Due to its many benefits, the Dual Active Bridge (DAB) DC-DC converter is always easy to find in micro grids applications, energy storage systems applications, vehicles to grid applications, and much more in the current energy architectures. Due to system changes and disturbances on both the input side and on the output side brought by the broad variety of applications, the DAB performs inadequately. The output voltage of the DAB is to be controlled and kept constant during system fluctuation with limited time response using a neural network based adaptive controller. The configuration of the proposed controller is identical to that of a PI controller. The study is done using MATLAB Simulink, where the system is tested under system variations. The proposed controller, a PI controller, and a combination of an AANN in parallel with a PI controller are all subjected to a performance test via time domain analysis. The results of the comparison between the three controllers favored the suggested controller.

Coriander is an integral part of South Asian cuisine and it is one of the most consumed leafy vegetables in south Asia. It is also a rich source of minerals and proteins. The delicate nature and low shelf-life lead to a high amount of wastage which can be avoided by drying. Solar drying is an efficient and economically justifiable method for drying coriander leaves. In the present work, PSTD and PSCD solar dryers are used for drying coriander leaves and the performance of these dryers at 0.5 m/s air velocity is monitored. During the experimental day, the ambient temperature ranged between 34 to 42 0C, and solar radiations varied between 584 w/m2 (Minimum) and 996 w/m2 (Maximum). The average air temperature inside the dryer chamber of both dryers is recorded as 10-150 C higher than the ambient temperature. The experimental results show that the drying time of coriander leaves can be significantly reduced by using the solar dryer. The developed PSTD outperforms the PSCD in terms of drying time, moisture reduction rate, instantaneous drying rate, and drying efficiency. The nutritional analysis tests of coriander leave before and after drying show that the quantitative retention of nutrients like total minerals, crude protein, crude fat, crude fiber, carbohydrates, and total energy is more in samples dried in a PSTD as compared to a PSCD. Nutritive tests also indicate that the drying process and type of dryer do not have a significant effect on the nutritional content of coriander leaves.

Technology advancements that happened in the last two decades have changed the way how people live, interact, and work more than any technology did in the past 100 years or so. Not only little “gadgets” enabled this enormous paradigm shift, the new innovative concepts have been well integrated into the design and manufacturing of computers, appliances, automobiles, airplanes, and ships, and it was about time to start seeing these concepts applied to the homes where building practices, by contrast, experienced a very slow, if not resistant effort to advance. At least they did before Virginia Tech demonstrated the use of advanced manufacturing concepts, prefabricated structures, and a great number of power electronics to redefine the conventional practice of modern home design. Its FutureHAUS won first place at the international competition in Dubai, UAE, validating an enormous societal desire to see this change finally happening. This paper will describe details of the electronic energy system implementation as well as an energy management algorithm developed to successfully achieve a net-positive energy balance in the FutureHAUS.

This paper proposed a two-stage electric vehicle (EV) on-board charger (OBC). The proposed charger is composed of a front-end ac-dc converter that is based on an interleaved buck-boost converter with reduced power electronics devices count. One of the main features of the proposed front-end ac-dc converter is the reduction of the inrush current due to the soft start-up capabilities. In addition, the buck stage helps to block and to isolate the fault current in case of dc-dc converter failure. Moreover, the proposed control algorithm for the front-end ac-dc converter regulates the dc output voltage and enables the converter to draw a sinusoidal current from the grid with a high power factor. The back-end dc-dc converter consists of a single active bridge (SAB) where the phase shift control is used to simplify the circuit of the proposed OBC. The back-end converter control loops enable operation under current control mode and voltage control mode for charging the battery bank. The PSCAD/EMTDC software package is used to simulate the proposed OBC and to evaluate the dynamic performance under different operating conditions.

Induction Motor (IM) restoration costs and downtime can be decreased by early Inter-turn short circuit fault (ISCF) detection. Due to the controller’s innate desire to generate an adjusted set of currents actually below fault conditions, fault detection of electric motors driven by an inverter with a model predictive control (MPC) algorithm becomes more difficult in inverter-driven applications. We suggest a novel actuation method in this contribution using the switching sequences produced by the Finite Control Set Model Predictive Controller (FCS-MPC) for ISCF of IM. based on diagnostics from neural networks (NN). Hence, no extra sensors or equipment are required for fault detection. This paper proposes a novel procedure for ISCF fault location of IM based on Neural Networks with Learnable Leaky ReLU (LeLeLU) function.

This paper proposes a new method to eliminate the limitations of conventional perturbations and observations (PO) of maximum power point tracking (MPPT) for wind energy conversion systems (WECS). The proposed algorithm based on multi-sector operation. The proposed MPPT algorithm divides the operating range into four sectors by comparing the power-speed curve and a parabola curve. Therefore, choosing an appropriate step size is related to the working area. The controller apply small steps to two sectors near the maximum power point (MPP). Otherwise, the controller uses a larger step size. The proposed technique has been validated on a large scale with MATLAB/SIMULINK with a 1.5 MW PMSG grid-connected WECS. The results shows that the efficient operation of this technology is based on improved efficiency and faster system response compared to conventional P& O technology.

This paper presents a comparative analysis between Class-D, Class-E and Class-EF power amplifiers for inductive Power Transfer (IPT) systems that operate at multimegahertz frequencies such as 6. 78MHz and 13. 56MHz. The design guidelines of all topologies along with components selection are presented. An open-loop system for each topology is built in LT-Spice simulator for verification and all classes are designed to feed a constant power load of 30W. Input DC voltage, total voltage stress and total current stress of all utilized switching devices, and efficiency are measured in the comparison between all topologies. Also, the soft switching operation for all topologies is obtained and validated for fair comparison to work effectively in the mentioned high frequency. The main feature of Class D is the simplicity of the passive elements design and operation. However, it has additional switch compared to class E. In contrast, Class E has higher efficiency between all counterparts with using one switching device but needs carful design criterion to solve dependent load issue. Finally, Class EF PA has a complex design process and has many component counts.
