Power electronic best components are most sensitive to variation in voltage and current. therefore these components when connected to a DC microgrid needs more attention and protection against a different type of circuit faults like short circuit and open circuit condition. During short circuit condition the flow of heavy current will damage the electronic devices and thereby in order to achieve the protection these electronic devices may trip themselves. sudden tripping of the devices will have an adverse negative impact on the DC microgrid. This paper presents a new ANN-enabled bat algorithm to detect the DC fault and to isolate the fault from the rest part of the system. Matlab simulink based model has been developed to test the prototype and to compare the ANN enabled bat algorithm with other algorithm for comparing the efficiency of the proposed algorithm.
电力电子的最佳元件对电压和电流的变化最为敏感。因此,当这些组件连接到直流微电网时,需要更多的关注和保护,以防止不同类型的电路故障,如短路和开路情况。在短路状态下,大电流的流动会损坏电子设备,从而实现对电子设备的跳闸保护。设备的突然跳闸将对直流微电网产生不利的负面影响。本文提出了一种新的基于神经网络的蝙蝠算法来检测直流故障,并将故障与系统其余部分隔离开来。建立了基于Matlab simulink的模型对原型进行测试,并将基于人工神经网络的蝙蝠算法与其他算法进行比较,以比较所提出算法的效率。

The use of electric vehicles is increasing exponentially in the real world, to limit the usage of fossil fuels and reduce air pollution. At some point in the near future, internal combustion engine mobility will be overtaken by E-mobility. To gain an advantage over the conventional internal combustion engine, E-mobility has to increase its range. This range extension can be done by battery swapping, or by wireless power transfer. Wireless power transfer is an exponentially growing technology, researchers are working tirelessly and there is rapid development concerning range, size, high frequency, and efficiency. Wireless power transfer is a safer, reliable, cheap, and convenient topology for charging electric vehicles. Dynamic charging of the electric vehicle battery will reduce the need for heavy, large capacity, and costly batteries. In this paper, a dynamic inductive type wireless power transfer for the two-wheeler and last-mile delivery electric vehicles is proposed. Dynamic inductive type wireless power transfer transfers power from AC/DC supply wirelessly and an isolated DC-DC full-bridge converter is implemented at the receiver side to meet the battery requirement. LCL compensating network is used to reduce harmonics and switching losses. Simulations for the proposed system was carried out for the dynamic charging of electric vehicle battery in Matlab and, a comparision of rate of change of SoC with and without isolated DC-DC full-bridge converter is evaluated.

Agricultural sector contributes 6.4% of total economic generation across the world. Notably, the utilization of technology to improve the yield and economy is rapidly increasing. To provide continuous supply to the residential customers, the agricultural feeder grid-dependency has to be integrated with Solar Photo Voltaic (SPV) systems. In this paper, an Artificial Eco-System based Optimization (AEO) algorithm is proposed for simultaneously identifying the locations and quantifying the sizes of SPV systems. A practical distribution system feeder ‘Racheruvu 11kV agricultural feeder’ Andhra Pradesh, India is considered for simulation purpose and the performance is compared with the standard IEEE-33 radial distribution system.

The description of coherent features in modern power grids is fundamental in understanding the underlying transient phenomena. While the system dynamics is large-scale and governed by strong nonlinear behavior, an efficient sparse representation can be formulated in a suitable coordinate system. One such representation is given by the Dynamic Mode Decomposition (DMD). In this contribution, we use DMD to obtain low-dimensional reconstructions of power system models from data obtained via a direct numerical simulation or a physical experiment. Notably, we show that DMD can describe the underlying oscillatory swing dynamics captured in data or project the large-scale solution manifold on a system having fewer degrees of freedom.

A single layer tri-band frequency selective surface (FSS) is proposed in this paper. It is composed of two transmission poles and one stop band filter, thus behaving as good isolation between two transmission bands .i.e. C and X-band. The design consists of two square slots with a center square patch and two cross dipole patch diagonally arranged in a two-dimensional unit cell. Two band pass filter is at 6.04 GHz and 9.60 GHz resonant frequency with a band width of 0.89 GHz and 0.87 GHz respectively. One stop band filter at 7.6 GHz resonant frequency in between these C-band and X-band play an important role for the good isolation for wireless communication. The size of unit cell FSS is 0.40λ0×0.40λ0 and thickness of 0.016λ0, where λ0 is the first lower resonant frequency. Both pass band resonant frequencies are spaced with a good shielding providing the frequency ratio of 1.57.

Automated segmentation of knee subchondral bone structures such as area and shape using deep learning approaches is a significant task for medical MRI images. However, existing techniques usually suffer from many challenges due to complex tissue structure when utilized in 3D due to their large memory requirements, and unusual image contrast/ brightness. This paper aims to exhibit proof of the concurrent effectiveness and reliability of the dynamic segmentation technique currently used to quantify 3D statistical shape/image-based in knee assessment and to propose suggestions for their utilization in the treatment of osteoarthritis disease. The proposed automated Hybrid UNet+Attention technique involves the enhancement of contrast of knee MRI bone surface images and can process large full-size 3D input samples (no patches) within seconds using the CPU. The overall performance of the proposed technique was estimated against ground truths by computing performance metrics like Intersection over union (IoU), dice similarity coefficient (DSC), precision, and recall.

This paper aims to exhibit proof of the concurrent effectiveness and reliability of the dynamic segmentation technique currently used to quantify 3D statistical shape/image-based in knee assessment and to propose suggestions for their utilization in the treatment of osteoarthritis disease. The proposed automated Hybrid UNet+Attention technique involves the enhancement of contrast of knee MRI bone surface images and can process large full-size 3D input samples (no patches) within seconds using the CPU. The overall performance of the proposed technique was estimated against ground truths by computing performance metrics like Intersection over union (IoU), dice similarity coefficient (DSC), precision, and recall.","PeriodicalId":251455,"journal":{"name":"2022 Trends in Electrical, Electronics, Computer Engineering Conference (TEECCON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122832812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, a novel nine-level inverter with quadruple boosting capability is proposed. The suggested topology is based on the switched capacitor approach and employs two capacitors, fourteen switches, and one DC source to provide nine output voltage levels. It features self-balancing of capacitor voltages and polarity is created inherently without the usage of H-bridge. For the creation of gate pulses, the level shifted pulse width modulation (LSPWM) scheme is employed, and voltage stress analysis is performed on all switches at each voltage level. Simulations based on MATLAB/Simulink are used to analyze and validate the proposed topology under various parametric changes.
本文提出了一种具有四倍升压能力的新型九电平逆变器。建议的拓扑结构基于开关电容方法,并使用两个电容、14个开关和一个直流电源来提供9个输出电压电平。它具有自平衡电容器电压和极性的固有不使用h桥。对于栅极脉冲的产生,采用了电平移位脉冲宽度调制(LSPWM)方案,并对每个电压电平下的所有开关进行了电压应力分析。基于MATLAB/Simulink的仿真分析和验证了所提出的拓扑在各种参数变化下的正确性。
