This research presents a generic pulse width modulation (PWM) approach for nine switch inverters and five-leg inverters. The circuit design of both inverters and a modulation mechanism for separate drives have been described. The available DC bus voltage supplied the two induction motors using a PWM technique for a 5-leg inverter. Nine-switch inverters and nine-switch z-source inverters have lately been presented as dual-output inverter. A nine-switch z-source inverter and a unique pulse width modulation (PWM) were created. Also, a five-leg inverter is modelled using Extended Two Arm Modulation (ETAM) scheme. The suggested modulation techniques were applied to control two machine drive systems with a single inverter architecture with a reduced switch count for pumping the water to house hold appliances. The comparative analysis of the two dual-output inverters is integral to this work.

The internal conversion Integrated solar panel is a new type of solar panel that would be integrated into a traditional roof, rather than being installed on top of it. This could be an interesting solution to some of the challenges associated with traditional solar panels, such as the need for a separate mounting structure and the potential for shading. It could also potentially be more aesthetically pleasing, as it would blend in more with the rest of the building. Solar energy has the potential to provide clean and affordable electricity, but traditional solar panels have some limitations. In this proposal, we propose a novel solution: modifying existing solar panels into integrated solar roofs. The panels are integrated with a cement base and a special glass on top of the plate, creating a traditional roof that generates electricity more efficiently.

The rising reception of electric vehicles (EVs) has featured the significance of creating progressed battery the board frameworks (BMS) that focus on security and effectiveness. This theoretical presents an outline of the most recent headways in EV BMS innovation, explicitly zeroing in on temperature and fire security highlights. Temperature the executives assumes a basic part in guaranteeing the ideal presentation and life span of battery frameworks. EV BMS with cutting edge temperature checking and control abilities are intended to moderate the gamble of overheating and warm out of control. These frameworks integrate complex sensors and calculations to constantly screen the battery’s temperature and manage it inside safe cutoff points. Fire assurance is one more significant part of EV BMS plan. Lithium-particle batteries, generally utilized in EVs, are vulnerable to warm out of control occasions that can prompt flames or blasts.

This paper describes a useful modulated, asymmetric full-bridge converter for sustainable solar PV applications. The suggested converter achieves zero-voltage switching (ZVS) on the main side’s power switches and reduces circulating current loss by utilizing a full-bridge architecture and an asymmetric control method. The blocking capacitor and the leakage inductance of the transformer operate in resonance to further provide the Zero Current Switching (ZCS) off for the output diode without the need for any further circuitry. Output diode reverse recovery is no longer a concern as a result. Additional connections to the input voltage include the power switch voltage stresses. Because of these features, the suggested converter has the infrastructure to reduce power losses. The buildings of renewable energy sources can benefit especially from it.

Lithium-based rechargeable battery modules are widely used in Electric vehicles (EV), which are likely to become the primary method of transportation in the coming years. EVs are major actors due to their zero emissions of dangerous gases and increased energy efficiency. Lithium batteries should be examined and adjusted regularly to maintain the EV system's safety, productivity, and reliability. Due to a large number of battery cells in EVs, a battery management system (BMS) is required. An EV's battery should be ready to provide both long-lasting power and high energy. The BMS makes decisions based on measurable parameters. Battery resistivity, volume, the status of charge estimation (SoC), state of health (SoH), power declining, and remaining useful life can all be predicted by employing three non-invasive battery measurements like the voltage, current, and temperature. This article is about a low-cost, high-performance BMS. The paper aims to design a cost-effective BMS without compromising its performance. MATLAB is used to simulate and test the suggested design.

In the recent decade, it is possible to use electric vehicles in a safe, cost-effective, and environmentally friendly manner, but only if accurate and trustworthy state parameter predictions are produced prior to their disposal. The state of health (SOH) of the lithium-ion batteries (LIBs) must be precisely forecasted in order to ensure that the LIB can operate safely. The inability of physical SOH estimators to cope with the dynamic character of SOH when operating in a highly nonlinear environment is a common limitation when operating in nonlinear environments. Traditional SOH estimation techniques have demonstrated that they have limits that can be overcome by data-driven methods. TCN, a new machine learning technique, combines the advantages of residual neural networks (ResNet) with the computing efficiency of neural networks to produce a technique that is both efficient and effective. The results of rgw simulation show that the proposed method has reduced placement cost, and also a TCN can accurately estimate the SOH of a LIB with an MSE error of less than 1% over the LIB lifetime. The performance of an electric car battery, which are numerous and diverse, can be anticipated more precisely using this approach.

Commercial off-the-shelf semiconductor devices cannot supply system solutions provided by ASIC products. Only a few of the most obvious benefits include lower system costs, smaller volumes and weights, and improved system performance. An ASIC design solution can sometimes be used in conjunction with analogue or mixed-signal designs, but doing so requires weighing various factors, such as the level of available market technology and quality vs. the investment required to set up a mixed-mode design environment and hire sufficient staff. Two mixed-signal devices have been developed using the proposed approaches, and one of those devices (e.g., ABACUS) is part of an ESPRIT project partially funded by the European Commission.

In the healthcare domain, the mortality rates are increasing unprecedentedly by shifting a critical patient from one hospital to another hospital due to the lack of necessary medical equipment. This arises the need to propose a novel mobile application, which can show the information about different hospitals with necessary equipment in a particular location. This paper has proposed the novel application to mange the information about different hospitals in the nearby localities of the user and also it is developed to provide a basic information about medicines. Further, in the case of emergency situations, the proposed application plays an indispensable role by assisting the user in taking the appropriate first aid measures.

Lack of inertia in inverter dominated utility grids and smart microgrids is a serious issue that needs to be tackled and to enable larger integration of renewable energy sources, which are usually interfaced to the grid using power electronic converters. Recently, it has been proposed to embed the dynamics of conventional synchronous machines into power electronic converters to operate them as virtual synchronous machines or synchronverters. Since, the power electronic converters do not have rotational inertia, the electrical energy storage provides the virtual inertia to the virtual synchronous machine. Although a virtual synchronous machine is physically a power electronic converter, its operation is governed by the mathematical equations of a synchronous machine. Virtual synchronous machine based inverters may play a major role in future microgrids since it can impart the inertial response to weak grids during sudden frequency transients. The inverters in a microgrid should be capable of operating in autonomous mode in addition to the grid connected mode. In this paper, the performance of a virtual synchronous machine based inverter operation in autonomous mode is analyzed. The simulation is done using MATLAB/Simulink and the simulation results are validated with the hardware experiments using OPAL-RT real time simulator.
