Study on Modelling and Analysis of a Dynamic Voltage Restorer (DVR) and Sinusoidal Pulse Width Modulation (SPWM) Based Controller

This work presents the application of dynamic voltage restorers (DVR) with three level inverter on power distribution systems for mitigation of voltage sags/swells at critical loads. DVR is one of the compensating types of custom power devices. An adequate modelling

Phase-Locked Loop Controller for Three-Phase Unified Power Quality Conditioner for Non-linear and Voltage Sensitive Loads

A new efficient control method for a unified power quality conditioner is created in this work, which can eliminate voltage changes such as sag and swell situations in distribution systems, as well as current and voltage harmonic isolation. The proposed
