High Voltage, EarlyView.ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.

Engineering Reports, Volume 8, Issue 7, July 2026.This study designs and simulates a capacitor‐supported dynamic voltage restorer (DVR) using Carrier PWM control to mitigate voltage sags, swells, and distortions in three‐phase distribution systems. The self‐supported DVR employs a DC‐link capacitor as an energy buffer, eliminating external storage needs. Control via Synchronous Reference Frame Theory (
