Carry Select Adder (CSLA) is a fast adder used in data-processing processors for performing fast arithmetic functions. From the structure of the CSLA, the scope is to reduce the area of CSLA based on the efficient gate-level modification. In this paper 128 bit Regular Linear CSLA, Modified Linear CSLA, Regular Square-root CSLA (SQRT CSLA) and Modified SQRT CSLA architectures have been developed and compared. However, the Regular CSLA is still area-consuming due to the dual Ripple-Carry Adder (RCA) structure. For reducing area, the CSLA can be implemented by using a single RCA and an add-one circuit instead of using dual RCA. Comparing the Regular Linear CSLA with Regular SQRT CSLA, the Regular SQRT CSLA has reduced area as well as comparing the Modified Linear CSLA with Modified SQRT CSLA; the Modified SQRT CSLA has reduced area. The results and analysis show that the Modified Linear CSLA and Modified SQRT CSLA provide better outcomes than the Regular Linear CSLA and Regular SQRT CSLA respectively. This project was aimed for implementing high performance optimized FPGA architecture. Modelsim 10.0c is used for simulating the CSLA and synthesized using Xilinx PlanAhead13.4. Then the implementation is done in Virtex5 FPGA Kit.","PeriodicalId":258978,"journal":{"name":"2013 International Conference on Circuits, Power and Computing Technologies (ICCPCT)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123440399","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}

It is important to define that noise is a significant problem in PD detection. Accordingly, the paper mainly deals with denoising of PD signals, based on improved WT techniques namely Translation Invariant Wavelet Transform (TIWT). The improved WT method is distinct from other traditional method called as Fast Fourier Transform (FFT). The TIWT not only remain the edge of the original signal efficiently but also reduce impulsive noise to some extent. Additionally Translation Invariant (TI) Wavelet Transform denoising is used to suppress Pseudo Gibbs phenomenon. In this paper an attempt has been made to review the methodology of denoising the partial discharge signals and shows that the proposed denoising method results are better when compared to other wavelet-based approaches like FFT, wavelet hard thresholding, wavelet soft thresholding, by evaluating five different parameters like, Signal to noise ratio, Cross correlation coefficient, Pulse amplitude distortion, Mean square error, Reduction in noise level.","PeriodicalId":258978,"journal":{"name":"2013 International Conference on Circuits, Power and Computing Technologies (ICCPCT)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125396609","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 for as, Indian environmental condition concern constant flow of the wind is an unexpected one. During the soft start of the wind turbine a fluctuation occurred and due to the change in the flow of the wind the revolution speed is changed. At the same time the output voltage is directly proportional to the speed of the DC generator connected with the wind turbine. Due to the fluctuation in the flow of air the output voltage is greatly disturbed, so that it is important to boost up the voltage and get constant output. DC to DC boost converters are particularly useful in stepping up the voltage from a battery or DC generator to match the operating voltage range of inverter or constant voltage loads. Even though lot of converters are introduced, the novel and advanced converter using the snubber capacitor is used in this proposed converter, it has more advantage and making the switching of the switches soft and boosting the voltage higher than the conventional boost converter in the same frequency and in same duty cycle. Here how the output is being constant in the variable voltage condition of the wind turbine by the boost converter and parameters used are investigated. Moreover, the various mode of operation of the boost converter during the transient period is discussed. The simulation model is generated and outputs are obtained by using Matlab Simulink.","PeriodicalId":258978,"journal":{"name":"2013 International Conference on Circuits, Power and Computing Technologies (ICCPCT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129519864","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}
