Research ArticleOpen accessIn the abstractPerformance Comparison of Three-Phase Shunt Active Power Filter AlgorithmsMoleykutty George, Kartik Prasad BasuThe usage of parallel converters is ever increasing. However, the voltage and current harmonics, zero-sequence and negative- sequence components of voltage and current and reactive power present in parallel converters give an alarming signal to power system and power electronic engineers. This research discusses performance of three-phase shunt active power filter (APF) system using three different control techniques namely synchronous … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractConfigurable Multirate Filter BanksAli Al-HajMultimedia communications require efficient and real-time implementations of multirate digital signal processing systems. The backbone structures of multirate systems are digital multirate filter banks. Therefore, efficient multimedia communications rely, in the first place, on real-time implementations of multirate filter banks. In this paper, we describe a Field Programmable Gate Array (FPGA) implementation of the analysis and synthesis filter banks which … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,379 accessesView PDFCite
