POWER QUALITY ENHANCEMENT USING DISTRIBUTED GENERATION INVERTER WITH ACTIVE POWER CONTROL

Abstract

Unlike traditional passive filters, modern active filters have the following multiple functions; harmonic filtering, damping, isolation
and termination, reactive-power control for power factor correction and voltage regulation, load balancing, voltage-flicker reduction, and/or
their combinations. Significant cost reductions in both power semiconductor devices and signal-processing devices have inspired manufactures
to put active filters on the market. This paper deals with general pure active filters for power conditioning, and specific hybrid active filters for
harmonic filtering of three-phase diode rectifiers, as well as traditional passive filters.
