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 ...

IET Power Electronics, Volume 18, Issue 1, January/December 2025.This paper eliminates the conventional high‐gain DC‐DC converter by a novel single‐source reduced‐switch common ground (CG) nine‐level switched capacitor (SC) inverter, which has quadruple boosting capability. The proposed inverter has eleven switches, among which nine switches are driven at higher frequency while being clamped by low capacitor ...

Dual Winding Induction Machine Based Grid‐Tied Inverting System
IET Power Electronics, Volume 18, Issue 1, January/December 2025.In this paper, we show a machine interface for renewable energy integration: a dual winding induction machine (DWIM) based inverting system. The DWIM‐based inverting system can effectively alleviate the problems such as wideband oscillations, inertia deficiency and weakened grid strength, caused by the high penetration of power electronic equipment ...

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.Abstract In this work, a novel switching method for the photovoltaic‐fed (PV‐fed) dynamic voltage restorer (DVR) system based on a quasi‐Z‐source inverter (quasi‐ZSI) is proposed. This proposed switching control strategy is implemented in such a way that a wider voltage boost gain and lower voltage stress across the switches and capacitors are achieved.
