Fuzzy Logic Controller based Bridgeless (BL) Isolated Interleaved Zeta Conver...IJPEDS-IAES
In recent times, high-brightness light emitting diodes (HB-LEDs) are
developing rapidly and it is confirmed to be the future development in
lighting not only because of their high efficiency and high reliability,
however also because of their other exceptional features: chromatic variety,
shock and vibration resistance, etc. In this paper, a bridgeless (BL) Isolated
Interleaved Zeta Converter is proposed for the purpose of reducing the diode
failures or losses; the value of output ripples also gets decreased. The
proposed BL isolated interleaved zeta converter operating in discontinuous
conduction mode (DCM) is used for controlling the brightness of LED
Driver with inherent PFC at ac mains using single voltage sensor. The fuzzy
logic controller (FLC) is used to adjust the Modulation Index of the voltage
controller in order to improve the dynamic response of LED Lamp driver.
Based on the error of converter output voltage, FLC is designed to select the
optimum Modulation Index of the voltage controller. The proposed LED
driver is simulated to achieve a unity power factor at ac mains for a wide
range of voltage control and supply voltage fluctuations.
MODELLING OF 200W LED DRIVER CIRCUIT DESIGN WITH LLC CONVERTERJournal For Research
LED is a recent technology, which has replaced all other conventional light sources in the past few years and since it is current controlled, accurate driver design is necessary. The LED driver should have the capability of providing constant current regardless of the LED forward voltage variations. The LLC converter is controlled to operate as a constant current mode LED driver. A 100 kHz, 200W LLC LED driver is designed and calculated to verify the proposed circuit and design method. This paper proposes mathematical model of 200W LED driver circuit design with LLC resonant converter. The proposed circuit uses a full bridge rectifier to convert AC to DC and increases the rectified output voltage using boost converter which is operated in continuous conduction mode and a quasi-half bridge resonant converter to drive the LED lamp load with coupling transformer. The LLC converter is designed such that solid state switches of quasi half bridge are working under zero switching scheme to reduce switching losses. The analysis, design and modelling of 200 W LED driver is carried out by mathematical model and stability analysis for universal AC mains.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
