Dynamic interaction and energy redistribution in shared DC-link multi-output CC–CV flyback converters fed by an MPC-controlled boost PFC

Abstract Multi-output Constant Current–Constant Voltage (CC–CV) power conversion systems are increasingly employed in battery charging applications because they enable multiple charging channels to operate from a common Direct Current (DC)-link. However, the dynamic interaction a...

Benchmarking autoregressive machine learning models for daily rainfall forecasting as a baseline for hydrological applications

Abstract Accurate daily precipitation forecasting is a prerequisite for efficient reservoir operations, irrigation scheduling, and urban flood management, yet inherent predictability limits pose a significant challenge. This study quantifies these limits by evaluating a suite of...

Enhance motor imagery EEG classification using DWT and chirplet transform

Brain Computer Interfaces promote seamless interaction between individuals with movement limitations and their surrounding environment by transforming electroencephalography signals derived using Motor Imagery. The procedure relies on accurately classifying various MI activities,...

Data-driven probabilistic evaluation of voltage stability limit considering joint wind uncertainties

Abstract The voltage stability limit (VSL) is crucial for power system operators to ensure grid security by defining the maximum loading before risking voltage collapse, thus preventing cascading events and maintaining reliable power supply. Higher proportion of renewable integra...

A Robust Machine Learning Framework for Assessment of Hydroclimatic Teleconnections between Monthly ISMR and 18 Circulation Indices and Prediction of Monthly ISMR

Abstract Rainfall received across the India during monsoon season is very crucial for the country’s economy. Predicting monthly rainfall plays a crucial role in efficient water resources management and in reducing the risk of hydrological disasters. Looking to the drawback of gen...

Wideband Compact Designs of Circular and Equilateral Triangular Microstrip Antennas Employing Rectangular Slots Cut Ground Plane

ABSTRACT Compact and wider bandwidth designs of proximity fed circular and equilateral triangular microstrip antennas backed by rectangular slots cut ground plane are proposed. Slot on the ground plane reduces the fundamental mode frequency on each of the patches that yield wideb...
