Analysis of the failure mechanism of ZnO varistors influenced by high‐resistance media based on multi‐field coupling simulation

High Voltage, Volume 10, Issue 3, Page 673-679, June 2025.
Abstract This study focuses on the distribution of high‐resistance media (pores and spinels) within ZnO $\text{ZnO}$ varistors and explores the mechanical and electrical failure mechanisms of varistors under different pulse actions. Micro‐CT technology revealed that the proportion of high‐resistance media in the edge area is much higher than in the ...

Control strategy of novel hybrid commutated converter based on reverse blocking integrated gate commutated thyristor for commutation failure mitigation

High Voltage, Volume 10, Issue 3, Page 546-554, June 2025.
Abstract Commutation failure (CF) is an inherent problem faced by line commutated converter high voltage direct current (LCC‐HVDC) technology. To completely solve the problem of CF, we have proposed a novel hybrid commutated converter (HCC) technology based on reverse blocking integrated gate commutated thyristor, which can utilise two methods for ...
