Modeling and Assessing Vulnerabilities of Aircraft Cyber–Physical Power Systems Based on Complex Network Theory

IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.
The concept of more electric aircraft (MEA) is a major trend in the aircraft industry. Compared to the conventional aircraft electrical power system (AEPS), the MEA–EPS has become more integrated and complex. The MEA–EPS demonstrates typical characteristics of a cyber–physical system (CPS) as a result of the implementation of intelligent management and

Systematic Implementation and Performance Evaluation of Multiphase Power Converter in Medium Voltage Drive System

IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT Investigation of power converters for use in industrial drive applications finds that these converters are used low reliable components. To overcome this issue, in this paper, advanced power converters (multi‐pulse AC–DC and multilevel DC–AC converter) are developed and implemented to feed vector‐controlled induction motor drive (VCIMD), which

A Novel Approach for Mitigating Electrical Losses and Current Unbalance in Low Voltage Distribution Networks

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
In this method, by increasing the degrees of freedom of the unbalanced IEEE 906 bus low‐voltage reference network through load transfer switches, the optimal network configuration is proposed using a meta‐heuristic algorithm to solve this constrained large‐scale optimization problem for the purpose of electrical losses reduction.

Design and implementation of a full analogue gate driver for current compensation of paralleled SiC‐MOSFETs

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
This paper designs and implements a fully analogue gate driver for current compensation of paralleled SiC‐MOSFETs. Silicon carbide MOSFETs have current ratings that are not sufficiently high to be used in high‐power converters. It is necessary to connect several MOSFETs in parallel in order to increase current capabilities.

An Isolated SEPIC‐Based AC‐AC Converter for Voltage Sag/Swell Mitigation

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
ABSTRACT This paper proposes a high‐frequency isolated buck‐boost AC‐AC converter based on the single‐ended‐primary‐inductance‐converter (SEPIC) topology and its extension circuit with bipolar output. The proposed converters can achieve a wide range of voltage step‐down and step‐up operations with both same‐ and reversed‐phase outputs.

Hybrid IGBT/IGCT‐Based DC‐Hub for Interconnection of VSC/LCC Future DC Networks

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
ABSTRACT The interest in interconnecting multiple DC grids‐ medium‐voltage direct current/high‐voltage direct current (MVDC/HVDC)‐ across the globe has grown significantly in recent years. This interest is primarily driven by the benefits of increased reliability and cost efficiency in power transmission systems, particularly with the growing ...
