Research ArticleOpen accessPhrase in the titleFuzzy Inference System Based Power Factor Correction of Three Phase Diode Rectifier Using Field Programable Gate ArraySundar Rajan Giri Thulasiraman, Christober Asir RajanThis study describes a novel method in improving the input current total harmonic distortion as well as power factor of a three-phase diode rectifier circuit. In this method, three bidirectional switches comprising MOSFET and four diodes are used across the three-phase supply and load. In a three-phase rectifier only two diodes conduct at any given time. As a result, the … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 6,877 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDesign of a Single-Phase Rectifier with Improved Power Factor and Low THD using Boost Converter TechniqueIsmail Daut, Rosnazri Ali, Soib TaibThe method of using Boost type of converter was proposed for a 300W single-phase rectifier in this paper. By designing the necessary techniques and methodology, the overall Power Factor (PF) and Total Harmonic Distortion would be improved to the expectation. The cause of having low PF and high THD for a diode-capacitor type of rectifiers is related to non-linearity of … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 7,127 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHARMONICS REDUCTION IN FRONT END RECTIFER OF UNINTERRUPTIBLE POWER SUPPLIES WITH ACTIVE CURRENT INJECTIONT. Chandrasekar, B. Justus Rabi, A. KannanHarmonics are the by-products of modern electronics devices so it is necessary to mitigate the harmonics and offer techniques to mitigation of harmonics. It is greatly hampered by a three phase rectifier used as a front-end ac-to-dc converter in many systems. High power factor is achieved by injecting high-frequency currents into the three-phase rectifier. This study presents the high power … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 6,803 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,418 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMultimode Controller Design for DSTATCOM integrated with Battery Energy Storage for Smart Grid ApplicationsSai Pranith, T.S. BhattiA Distribution Static Compensator (DSTATCOM) can provide reactive power support, power factor correction and voltage regulation to a distribution system feeder. In this paper, a multimode multifunctional control algorithm is proposed for the controller of the Voltage Source Converter (VSC) to provide DSTATCOM and load leveling functionalities for smart grid applications through a Battery Energy Storage System (BESS) connected to … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 26 Oct 2017 · 8,399 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling and Simulation of a Novel Switched Reluctance Motor Drive System with Power Factor ImprovementG. Venkatesan, R. Arumugam, M. Vasudevan et al.This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,096 accessesView PDF Cite
