Segment Reduction‐Based SVPWM Applied Three‐Level F‐Type Inverter for Power Quality Conditioning in an EV Proliferated Distributed System

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
The objective of this paper lies in the realization of a three‐level F‐type inverter (3L‐FTI) as a shunt active filter in an EV‐proliferated environment. The switches are triggered using segment reduced space vector pulse width modulation (SVPWM). This modulation technique provides a lower number of switching transitions than existing PWM strategies ...

Servo Control of Shunt-Active Power Filters Using Kalman Filter With DC-Link Reference [PDF]

E3S Web of Conferences
LQG servo controllers may regulate current flow in a SAPF (shunt-active power filter) provided by a balanced or unbalanced supply voltage. Balanced or uneven supply voltages power the SAPF.

Optimizing Power Flow in Photovoltaic‐Hybrid Energy Storage Systems: A PSO and DPSO Approach for PI Controller Tuning

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
This paper focuses on developing power management strategies for hybrid energy storage systems (HESSs) combining batteries and supercapacitors (SCs) with photovoltaic (PV) systems. The proposed control scheme is based on proportional‐integral (PI) controllers optimized with particle swarm optimization (PSO) and duplicate particle swarm optimization ...

An Attention‐Based Detection Method of Fatigue Cracks on Steel

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Steel structures are susceptible to fatigue cracking under cyclic loading, which can lead to catastrophic structural failure. In the incipient phase of crack propagation, the width of fatigue cracks typically measures less than 0.1 mm, making them difficult to detect using standard imaging techniques.

Harmonic oscillation analysis and stabilization method comparison of shunt active power filter in full compensation mode

IET Power Electronics
The harmonic compensation of SAPF (shunt active power filter) may trigger harmonic oscillation due to the interaction with grid impedance and non‐linear loads, which distorts the power quality.
