Motor overvoltage mitigation using SiC-based zero-voltage switching inverter [PDF]
The motor overvoltage phenomenon is an issue that may arise from the high voltage slew rates ( dv/dt ) of silicon carbide MOSFETs in cable-fed drives. This can lead to substantial strain on cable and motor insulation, resulting from partial discharges ...

High Voltage, EarlyView.ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.

IET Smart Energy Systems, EarlyView.A hybrid GA–PSO framework determines the optimal placement and sizing of distributed battery energy storage systems in a PV‐enriched low voltage feeder, whereas dynamic consensus control (DCC) coordinates their operation. The integrated approach mitigates voltage rise and reverse power flow and promotes balanced utilisation of multiple storage units ...

Applied Research, Volume 5, Issue 5, October 2026.A digitalised Aids‐to‐Navigation monitoring system (ARMS) was deployed across 478 installations in the Strait of Malacca and Malaysian waters, integrating multi‐sensor edge validation, hybrid AIS/VHF/cellular communication, and a centralised platform. It achieved 98.3% availability and cut fault‐detection time from weeks to just 8.4 min.
