Active Rectifier with Extended Functions: An Option to Voltage Sags Ride Through and Power Quality Improvement

Abstract

The power quality concept, is usually confused with energy saving. However, even if energy saving is desirable over all in industry applications, the first concept does not implie the second one. For the electrical engineers, the improvement of power quality using the existing converters is a great challenge. This paper deals with a multilevel, single phase active rectifier whose main objective is to compensate power factor which, with an adequate control, provides voltagesag compensation and power quality conditioning.
