IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.Large‐capacity high voltage direct current (HVDC) transformers are the core equipment of the future power system. The design and operation of these transformers involve the interaction of multiple physical fields. The use of multiphysics simulation technology can comprehensively consider the coupling effects of various physics, which can help optimise ...

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.1. A refined component‐level reliability model for four‐port soft open points (SOPs) is developed, explicitly incorporating correlations among sub‐modules (SMs) of hybrid modular multi‐level converters (MMCs). 2. A load restoration optimisation model is formulated, explicitly integrating SOP fault modes to achieve optimal load recovery via multi‐device

IET Power Electronics, Volume 18, Issue 1, January/December 2025.In this paper, applied heating was shown to effectively inhibit dendritic corrosion growth, formed in the power module isolation trenches in corrosive environments, by reducing the effective relative humidity and thereby the thickness of the adsorbed water layer on the ceramic substrate surface. The findings can be applied to enhance the reliability of

IET Power Electronics, Volume 18, Issue 1, January/December 2025.Inertia, critical for power system stability, is diminished as synchronous generators are replaced by low or no‐inertia renewable resources, threatening microgrid stability. To address this, grid‐forming converters (GFMC) are controlled using energy transfer characteristics, adapting separately excited DC machine equations for DC microgrids. Simulation

Impeding Dendritic Corrosion in Silicone Gel Potted Power Module Isolation Trenches by Heating
IET Power Electronics, Volume 18, Issue 1, January/December 2025.Environments with high humidity and corrosive gases have been shown to cause dendritic corrosion growth in the isolation trenches of power semiconductor modules. In time the dendrites can short the isolation trenches, causing failure of the component and the device.
