Research ArticleOpen accessIn the abstractMicrocontroller Based Power SupplyTanvir Singh Mundra, Er. Satwinder Singh Sachdeva, K.S. KahlonThese days, majority of electronic devices work on DC power source, so there was a requirement of a reliable and customized power supply. Generally, the requirements are not too varied, but still they require every time a new hardware designing. The idea presented here is to build a microcontroller controlled power supply[1] that is flexible enough to meet different customer … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 6,781 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalysis of the Over-Voltages Produced by Lightning Strokes in the Power Transmission System in the Southern Region of Saudi ArabiaA. U. Al-Abdulaziz, S. M. Bashi, A. A. AlthubaitiThis study deals with the simulation of lightning strokes and their effects on power network in the southern region of Saudi Arabia. The network consists of main generating stations, substations and the power transmission lines. The transient performance of the system has been investigated using the EMTP (Electro Magnetic Transient Program). Some surges were introduced to the network as in … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,213 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

Research ArticleOpen accessIn the abstractA Fully Integrated Dual-Band Low Noise Amplifier for IEEE 802.11 and Hiper LAN ApplicationMow Shouxian, Ma Jianguo, Yeo Kiat Seng, Do Manh AnhA fully-integrated dual-band Low Noise Amplifier (LNA), which can be used for IEEE 802.11 and Hiper LAN applications, was investigated in this paper. The proposed LAN was implemented entirely pm a single chip based on a standard 0.18 μm 1P6M CMOS process. It draws 13 mA current from a 1.5-V voltage supply and achieves power gains of 17 and 10 … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,288 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltra Low Power MUX Based Compressors for Wallace and Dadda Multipliers in Sub-threshold RegimePriya Gupta, Anu Gupta, Abhijit AsatiThe computing efficiency of modern column compression multipliers offers a highly efficient solution to the binary multiplication problem and is well suited for VLSI implementations. The various analyses are established more on compressors circuits particularly with Multiplexer (MUX) design. Conventionally, compressors are anatomized into XOR gate and MUX design. In this study, fully MUX based compressors, utilizing the CMOS transmission … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 17 Nov 2015 · 8,612 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordImplementation of a Novel Control Strategy Using Fuzzy Logic Controller to Shunt Active Filter for Line Harmonic ReductionN. Senthilnathan, T. ManigandanProblem statement: Now days, power quality has been given attention due to the intensive use of power electronic equipments in all types of industries such as steel, paper, textile industries and so on. These power electronic devices induce harmonic distortion into the supply lines which gives rise to many undesirable effects. Approach: This study presents a new method for harmonic … …Journal of Computer Science, Vol. 8, Issue 5 · 29 Feb 2012 · 7,087 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordControl 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 accessAll words, across the recordHarmonic Elimination of Inverters using Blind Signal SeparationB. Justus Rabi, R. ArumugamHarmonics cause major problems in power system due to non linear loads. With the rapid growth in the utilization of the rectifier for critical loads, e.g. In computer or medical equipment the need for high quality uninterruptible power is increasing. The non-linear current drawn by the rectifier loads distort the output of UPS system. Mainly because of output filter impedance … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,899 accessesView PDF Cite
