Research Progress on Electrical Insulation Under Superimposed Voltage With High‐Frequency Harmonics in New‐Type Power Systems

High Voltage, EarlyView.
ABSTRACT A new‐type power system serves as a critical technical support for the integration of new energy, and its secure and stable operation is of great importance. However, the extensive utilisation of power electronic devices leads to power equipment insulation being subjected to electrical stresses of high‐frequency harmonics, which can easily ...

Microscopic Stress Analysis of Silicon Carbide Devices Under Overcurrent Conditions in DC Solid‐State Circuit Breakers

IET Smart Energy Systems, EarlyView.
A coupled Saber–TCAD–thermo‐mechanical simulation framework is proposed to evaluate microscopic stresses in SiC MOSFETs under overcurrent operation. Ultrahigh gate‐voltage driving reduces thermal and mechanical stress but increases gate oxide electric‐field stress, revealing a reliability tradeoff for DC solid‐state circuit breakers.

Development of a Framework for Modelling Adhesive and Bulk Fracture in Ice: Application to Electroexpulsive Ice Protection Systems

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study proposes a modelling framework for ice adhesive and bulk fracture. In this framework, adhesive and bulk fracture mechanisms are treated as distinct phenomena. Adhesive fracture is modelled using the well‐established cohesive zone model, which is widely used in the analysis of composite material delamination.
