IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This study explores fault diagnosis methods for PWM inverters in a wind energy conversion system using a doubly fed induction generator. Two intelligent diagnostic techniques, fuzzy resonant logic and artificial neural networks, are proposed. The fuzzy logic method monitors inverter faults in real time, whereas the neural network method uses 3D feature

A three‐phase three‐level converter with shared flying capacitors
IET Power Electronics, Volume 19, Issue 1, January/December 2026.Three‐phase multilevel converters use a high number of components which increases their size. As specific weight reduction is a work of interest for embedded system applications, this paper presents a topology aiming to optimize volume and mass for a three‐level three‐phase inverter. The number of passive and active components is reduced thanks to the ‘
