Comparative study between fuzzy logic and artificial neural network (ANN) algorithms for single phase shunt active power filters (SAPFs) [PDF]

, 2013
The excessive use of power electronics devices in industrial, commercial and residential purposes have lead to the deterioration of supply current and voltage wave forms, injecting harmonic pollution on to the supply system, which no doubt generates a ...

Analytical Frameworks and Theories of Electric Power in Non‐Linear Circuits

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Based on the challenges of distorted currents and non‐linear components in modern power grids, this article reviews seminal electrical power theories that seek to generalize the traditional definitions of active, reactive, and apparent power. It provides a detailed analysis of their mathematical foundations, practical implementation, and validity.

Active Power Filter‐Based Low‐Frequency Ripple Power Suppression of the DC‐Link in Railway Traction Systems

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article presents an active power filtering control method to suppress ripple power in the DC‐link of railway traction systems, including both the inherent second‐order ripple of single‐phase rectifiers and additional frequency ripples introduced by the pantograph–catenary arc.

Phytoplankton iron limitation in the Atlantic Southern Ocean driven by seasonal mixed‐layer dynamics

Limnology and Oceanography Letters, Volume 10, Issue 6, Page 877-887, December 2025.
Abstract Phytoplankton blooms in the Southern Ocean (SO) are seasonally limited by light and micronutrients. As such, regional variations in iron supply from mixed‐layer winter entrainment are expected to impact the extent of seasonal iron limitation. Here, we determined seasonal iron limitation in the Atlantic SO by conducting iron addition incubation
