Temperature rise in a 3ϕ, Totally Enclosed Fan Cooled (TEFC)., Squirrel Cage Induction Motor (SCIM) used in Electric Vehicles (EV) is effected by core loss. The temperature rise is a function of core loss and other losses. Since, the core loss components eddy current and hysteresis losses are a function of flux and flux density, Finite Element Method (FEM) is used to obtain average maximum flux density at different loads. Core loss is varying with respect to load and hence temperature rise, resistance value, starting torque to maximum torque $(displaystyle frac{T_{st}}{T_{max}})$ ratio and current drawn at $(displaystyle frac{T_{st}}{T_{max}})$ also varies which is so far assumed constant in reality. The analysis is made on the effect of core loss on SCIM used in EV for performance enhancement. The results reveals that when the variable core loss is considered, temperature rise is reduced and the SCIM rating is enhanced for 20%.

The paper presents a new common ground single-phase transformerless five-level inverter for Photovoltaic (PV) applications. The topology is built with a minimum of six switches and three capacitors compared to various five-level inverter proposed in the literature and has the advantage of 100% dc-link utilization. The topology has the capability to supply both real power and reactive power. In order to achieve this, a simple level-shifted pulse width modulation scheme is used and proportional-resonant (PR) controller is developed to study the dynamic response of the system under input voltage as well as grid current changes. The performance of the proposed topology and their control scheme is validated through MATLAB simulation results. Finally, a detailed comparison is made with the recent five-level inverter topologies to highlight the merits of the proposed topolozy.

High-frequency unipolar High Voltage (HV) pulses find diverse applications, serving as a vigilant shield for safe-guarding a range of sites from buildings and livestock enclosures to vast agricultural expanses and international borders. Developing a Power Energizer circuit (PEC) holds great importance for a wide range of protective applications. This is powered by solar PV that is connected to a DC-DC boost converter, also has a battery backup that is connected to a bi-directional DC-DC boost converter. The performance of the PEC is proposed under various solar irradiance conditions and also under the safe limits of the energizer provided by IEC 60335-2-76:2002 standard [1]. The key feature distinguishing the PEC is its capability to generate HVP, exceeding 15 kV in magnitude, sustained for a microsecond. This is achieved while maintaining a continuous supply of nearly 48 volts for the input DC source, with the discharged pulse conforming to power energizer standards, yielding an energy level of approximately 5 joules.

This study focuses on enhancing the performance of a Doubly Fed Induction Generator (DFIG) performance in wind turbine applications through comparison and assessment conducted with advanced control schemes. It employed a stator flux-oriented vector control with a conventional PI controller. Still, it exhibited various drawbacks, such as ineffective active power control, inability to handle reactive power control, and difficulty sustaining DC link and stator terminal voltage within tolerable limits during severe disturbances. To overcome these drawbacks, an integration of a Fuzzy Logic Controller (FLC) was presented by replacing the PI controller in the control scheme, enhanced active power, reactive power, and DC link voltage control, abridged fluctuations, and improved the dynamic response of the DFIG system. Despite significant improvements accomplished with the FLC, some undamped oscillations persisted during disturbances. To further enhance DFIG's performance and effectually reduce power oscillations, a Power Oscillation Damping (POD) system was integrated into the control scheme. It continuously monitored the system for power oscillations and adapted the control signals to the Rotor-Side Converter (RSC) to counteract and dampen them. It dampens power oscillations during disturbances, resulting in a highly efficient, stable, and reliable DFIG system. The effectiveness and robustness of the proposed approaches are validated using OPAL-RT for the DFIG system.
本研究的重点是通过比较和评估先进的控制方案，提高双馈感应发电机（DFIG）在风力涡轮机应用中的性能。它采用了定子磁通矢量控制和传统的 PI 控制器。尽管如此，它仍然存在各种缺点，如有功功率控制效果不佳、无法处理无功功率控制，以及在严重扰动时难以将直流链路和定子端电压维持在可容忍的范围内。为了克服这些缺点，提出了一种模糊逻辑控制器（FLC）集成方案，取代了控制方案中的 PI 控制器，增强了有功功率、无功功率和直流链路电压控制，减少了波动，并改善了 DFIG 系统的动态响应。尽管 FLC 取得了重大改进，但在扰动期间仍存在一些未阻尼振荡。为了进一步提高 DFIG 的性能并有效减少功率振荡，控制方案中集成了功率振荡阻尼（POD）系统。该系统持续监测系统的功率振荡，并调整转子侧逆变器（RSC）的控制信号，以抵消和抑制功率振荡。它能抑制扰动期间的功率振荡，从而实现高效、稳定和可靠的双馈变流器系统。我们使用 OPAL-RT 对 DFIG 系统的有效性和鲁棒性进行了验证。

The widespread adoption of electric vehicles (EVs) grapples with a significant challenge known as ‘range anxiety’, which is the fear of depleting the battery charge before reaching the destination. This paper proposes an inventive strategy to mitigate range anxiety by integrating Vehicle-to-Vehicle (V2V) charging as a fundamental component of the EV ecosystem. The V2V charging mechanism harnesses the energy-sharing capabilities of EVs, facilitating power exchange between vehicles on the road. Our research targets the integration of solar panels onto the source vehicle, serving as a renewable energy source for V2V charging. The discussion commences by addressing the current state of range anxiety and the constraints of traditional EV charging infrastructure. The paper elucidates the design and implementation of a solar panel system on the source vehicle, emphasizing its efficiency and energy generation potential. To validate our claims, simulation results conducted in the MATLAB/Simulink environment are presented, offering a comprehensive analysis of the proposed V2V charging system's effectiveness. This paper significantly contributes to the growing body of knowledge surrounding innovative solutions for the EV industry. It underscores the potential of V2V charging, in tandem with solar panels, as a promising stride towards a more sustainable and range-anxiety-free future for electric vehicle users. The primary targets of this paper encompass elucidating V2V charging, detailing solar integration, conducting simulations, and analyzing results to provide valuable insights for the advancement of electric vehicle technology.

In recent years the growth of electric vehicles has increased day by day and this encourages the different G2V, V2G, V2V, V2L, and V2H technologies. In this paper, discussed the bidirectional power flow from the grid to the vehicle or vice versa. V2G technology is very beneficial during peak load periods, voltage regulation, and improvement of power system stability. To implement this V2G technology, it required proper management of the electric battery charger and the charger is capable of flowing the power in either direction. This paper shows the single-stage and dual-stage charger topology to flow the power in either direction i.e. G2V or V2G. This paper also shows the battery can be charged using constant current and constant voltage charging methods. In the single stage, use only the PFC circuit to charge or discharge the battery. In the dual-stage, an active bridge rectifier for AC to DC conversion with an L filter in series with the source has been used and for the next stage, a bidirectional DAB converter with an LC filter for DC to DC conversion is used and a separate control strategy for battery charging & discharging. This paper shows the battery control strategy can charge or discharge the battery at constant current and constant voltage. The performance of this single-stage and dual-stage battery charger is verified by simulations in MATLAB/SIMULINK software and the waveform is verified in real-time using the OPAL-RT system.

The toxicity issue is a major obstacle to the broad commercialization of Lead (Pd)-based Perovskite Solar Cells (PSCs). In such scenarios, Tin (Sn)-based PSC can be crucial to the widespread adoption of high-performance SC. In this study, a Sn-based structure of FTO/Ti02/CH3NH3SnI3/Spiro-OMeTADI Au has been proposed. A sequential strategy is adopted to evaluate the energy level, recombination rate, the bandgap of the absorber, work function, reflective coating, temperature, typical J - V and Q- E curve of the structure using SCAPS ID software. The optimized structure attained maximum power conversion efficiency (PCE) of 26.95 %, with open-circuit voltage (Voc) of 0.9622 V, short-circuit current density (Jsc) of 33.87 ma/cm2 and fill factor (FF) of 82.69% at 300k.

This paper introduces a solution using a single-phase single-stage PV transformerless five-level inverter to address leakage current issues. By utilizing a single PV source, the proposed inverter generates five output voltage levels. The design involves cascading two converters to achieve the proposed single-phase single-stage PV transformerless five-level inverter. Operating in both buck and boost modes, the proposed single-phase single-stage PV transformerless five-level inverter demonstrates distinct output voltage peak values: matching the input PV voltage in buck mode and doubling the input PV voltage in boost mode. The paper elaborates on the switching states necessary to produce these five output voltage levels in both operational modes. The key innovation lies in maintaining a constant common-mode voltage, effectively reducing leakage current. This feature remains consistent in both buck and boost modes. Additionally, the paper includes simulation results validating the functionality of this proposed single-phase single-stage PV transformerless five-level inverter.

The designed PMSM has been designed to deliver 300 W output power, produce 0.28 Nm torque and operate at 10110 rpm with 28V DC supply voltage. Spoke type rotor has been preferred in PMSM design. This design not only ensures magnet integrity under high rotation speeds, but also increases the flux density in the air gap, significantly increasing torque output. Improved torque output contributes to the UAV's maneuverability, allowing rapid adaptation to evolving mission demands.
无人驾驶飞行器（U A V s）的快速发展导致对高效、可靠推进系统的需求不断增加。本研究的重点是设计和开发一种专为微型无人飞行器设计的永磁同步电机（PMSM）。所设计的 PMSM 输出功率为 300 W，扭矩为 0.28 Nm，工作转速为 10110 rpm，直流电源电压为 28V。在 PMSM 设计中，辐条式转子是首选。这种设计不仅能确保磁铁在高转速下的完整性，还能增加气隙中的磁通密度，显著提高扭矩输出。扭矩输出的提高有助于增强无人机的机动性，使其能够快速适应不断变化的任务需求。
