Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.In the steel industry, electric arc furnaces (EAFs) are essential for metal scrap recycling. However, they are known for their high reactive power consumption, negatively impacting power quality (PQ). The static VAR compensator (SVC) is the reactive power compensation device that provides the best cost‐benefit relation for mitigating the impact of EAFs.

IET Power Electronics, Volume 17, Issue 16, Page 3005-3016, 16 December 2024.This article proposes a new identical bipolar buck‐boost AC‐AC converter with integrated coupled inductors. It possesses all the critical features of a bipolar buck‐boost topology, providing both in‐phase and anti‐phase output voltages. Compared to its counterparts, a high boost factor is achieved without large duty ratios due to using magnetic ...

Application of a three‐phase unified power quality conditioner in a microgrid
IET Smart Grid, Volume 7, Issue 6, Page 872-890, December 2024.The UPQC system designed in this study used a series inverter to compensate the voltage balance sag–swell component, providing a stable voltage for the back‐end load. When the load was unbalanced, the feeder current was unbalanced. The shunt inverter compensated for the unbalanced current balanced the feeder current to improve power quality.
