A Review of Control Techniques and Energy Storage for Inverter‐Based Dynamic Voltage Restorer in Grid‐Integrated Renewable Sources

open access: yesMathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
Power quality (PQ) is a key issue, particularly for technologically advanced process equipment, whose performance mainly depends on the quality of supply. Problems with PQ such as voltage swells/sags, interruptions, and harmonics are defined by any voltage, current, or frequency abnormalities causing damage or failure of the end‐user equipment. Outages

A Multi‐Objective Optimal Synchronous Modulation Strategy for Three‐Level Converter Through Switching Angle Regulation

open access: yesIET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a novel power loss reduction PWM (PLRPWM) strategy for three‐level neutral point clamped inverters. The proposed strategy aims to achieve multi‐objective optimisation by balancing low output harmonics, reduced switching losses and a balanced neutral‐point potential. ABSTRACT Three‐level neutral point clamped (3L‐NPC) converters have
