Rapid industrialization and its automation on the globe demands increased generation of
electrical energy with more reliability and quality. Renewable energy (RE) sources are …

This paper presents a comprehensive review on the unified power quality conditioner
(UPQC) to enhance the electric power quality at distribution levels. This is intended to …

Active filtering of electric power has now become a mature technology for harmonic and
reactive power compensation in two-wire (single phase), three-wire (three phase without …

Attention has been paid to active filters for power conditioning which provide the following
multifunctions: reactive power compensation; harmonic compensation; flicker/imbalance …

This paper deals with unified power quality conditioners (UPQCs), which aim at the
integration of series-active and shunt-active power filters. The main purpose of a UPQC is to …

In recent years there has been considerable interest in the development and applications of
active filters because of the increasing concern over power quality, at both distribution and …

In this article, common nonlinear loads have been characterized into two types of harmonic
sources, current-source type of harmonic source and voltage-source type of harmonic …

This paper presents a new synchronous-reference-frame (SRF)-based control method to
compensate power-quality (PQ) problems through a three-phase four-wire unified PQ …

Recently utilities are continuously seeking cost-effective and accurate power quality (PQ)
improvement techniques in order to achieve customer satisfaction. This paper intends to …

A new type of multilevel inverter is introduced which is created by cascading two three-
phase three-level inverters using the load connection, but requires only one dc voltage …
