This type of model avoids use of extra converter and use of battery which reduces the cost of whole system. The Solar water pumping system has becoming more popular in recent years. Photovoltaic (PV) cell having non linear P-V characteristics, it varies with changing solar radiation. Maximum power point tracking (MPPT) algorithms are used to track the peak power point, which helps to improve the efficiency of the system. The MPPT algorithms are incorporated with DC-DC converter which helps to track the MPP of PV cell. The Advantage of SEPIC converter is reduce the ripple at the output stage and also gives the same polarity as input polarity, which feeds the DC motor, so that the motor runs smoothly without any jerking moments, therefore life the DC motor will be increased. The proposed system is tested with different insolation conditions by changing the solar radiation and observed the DC motor characteristics. The P&O algorithm is used to track the MPP point according to changes in solar insolation and tested using MATLAB SIMULINK model and observed all the results.","PeriodicalId":431894,"journal":{"name":"2016 International Conference on Circuit, Power and Computing Technologies (ICCPCT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117334499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As spectrum is limited and expensive, unutilized spectrum is an economic constraint for the service provider. Cognitive radio provides a solution for this by providing means of reallocating the unused spectrum to secondary user (SU) when part of spectrum is unused by primary users (PU). Several past works have addressed this issue using various algorithm which ranges from statistical analysis to predictive analysis. In this paper we propose a novel solution for spectrum sensing using frequency domain analysis of the transmitted data. However one of the lesser addressed issues in this direction has been the consideration of PU emulation attack. If a SU has sufficient means of estimating void spectrum, then it can emulate a PU spectrum which then results is low accuracy in void spectrum detection. In this work we primarily focus on frequency domain analysis for void spectrum detection such that free spectrum can be padded up to prevent emulation attacks. We consider a cognitive radio network and adopt BPSK transmission. We assume that the access points are time synchronized and have preliminary knowledge of beginning of a transmission cycle. FFT of signal data in a time slot reveals the energy in the bands. By adaptive thresholding the energy of distinct bands we determine the free spectrum. Further we also demonstrate the means of reallocating this band by injecting secondary user data in the spectrum. We analyze the solution under AWGN channel. Comparison with QR based spectrum sensing technique reveals that the proposed work provides better sensing under high noise by triggering fewer false alarms and through more accurate prediction of the unused spectrum.","PeriodicalId":431894,"journal":{"name":"2016 International Conference on Circuit, Power and Computing Technologies (ICCPCT)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123056005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective of this design is to achieve Low power and high speed. Hybrid logic style used is the combination of C-CMOS logic (Complementary Metal Oxide Semiconductor) and Transmission gate (TG) logic. The Circuit was implemented using Microwind tool in 90 nm and 180 nm technology. Performance metrics of power and speed are compared with existing adder designs such as conventional CMOS adder, Transmission gate adder (TGA) and Transmission Function adder (TFA). Average Power consumption of the proposed design is found to be 1.114 μW at 90 nm for 1.2 V supply and 5.641 μW at 180 nm for 1.8 V supply. Delay in the signal propagation is measured as 0.011 ns and 0.087 ns for 90 nm and 180 nm technologies respectively. Thus consuming extremely low power and requires less time than existing designs for the same testing environment. Power Delay Product (PDP) is calculated as product of Power and delay values signifies energy requirement of the design. Proposed design requires 71% less energy than TFA and 81% less energy than TGA and 92% less energy than conventional CMOS adder.","PeriodicalId":431894,"journal":{"name":"2016 International Conference on Circuit, Power and Computing Technologies (ICCPCT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123275272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The supply of high grade electrical services required to the customers illustrates this concept. The voltage sag and swell are the most frequent PQ problems that mainly occur in the distribution systems since it may cause equipment tripping, failure of drive systems, shutdown for domestic and industrial equipment. The Dynamic Voltage Restorer (DVR)connected in series has magnificent dynamic capabilities and is a flexible solution for PQ problems. Ultra-capacitors (UCAP)have ideal characteristics such as high power and low energy density essential for the mitigation of voltage sag and swell. This paper presents an enhanced DVR topology capable of delivering deep, extended mitigation for power quality problems. In the proposed DVR, UCAP is used as energy storage as it provides excessive power in a short interval of time. The DVR is integrated into Ultra-capacitor via bidirectional DC-DC converter which supports in presenting a rigid dc-link voltage, and also helps in compensating temporary voltage sag and voltage swell. PI Controller is used in DVR for power quality enhancement. The simulation model for the proposed system has been developed in MATLAB and the performance over conventional DVR is validated with the results obtained.","PeriodicalId":431894,"journal":{"name":"2016 International Conference on Circuit, Power and Computing Technologies (ICCPCT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128813784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
