In such applications, an accurate and fast detection of the phase angle, amplitude and frequency of the grid voltage is essential for reference current generation. Phase angle plays an important role in control being used to transform the feedback variables to a suitable reference frame in which the control structure is implemented. Hence grid synchronization has a significant role in the control of grid connected inverter system. However, accurate on-line tracking of phase angle of the grid voltages under distorted grid condition is critical especially; during line notching, voltage unbalance, voltage dips, frequency variations etc. This paper presents phase estimation technique for grid synchronization using CORDIC algorithm with Synchronous Reference Frame-Phase Locked Loop (SRF-PLL) during unbalanced three-phase grid voltage conditions. By proposing CORDIC algorithm with SRF PLL, we can largely reduce the computational time while it will be implemented in real time platform using FPGA or DSP. Computer simulations have been carried out using MATLAB-Simulink package for feasibility of the study.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122899318","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}

And also, to check whether is the composite suitable for optical waveguide. There is an increasing commercial demand for nanoparticles due to their wide applicability in various areas such as optics, electronics, catalysis, chemistry, energy and medicine. Noble metal particles such as silver and gold are of great significance due to their size-dependent optical properties. Development of new nanomaterials with metal nanoparticles (Ag, Au, etc.) deposited on oxide surfaces, embedded within pores or encapsulated in its matrices have gained much attention. The prepared solution was deposited on high purity and polished glass substrate using spin coating in the fabrication process. The precise thickness control was achieved by using the layer-by-layer deposition technique. The films are deposited on microscopic glass slides with thicknesses ranging between 1000 and 4000 nm were prepared by a multi-layer process. Films which are characterized by UV Spectroscopy and AFM. Chemical composition of the particles was investigated by X-ray photoelectron spectroscopy (XPS). Fourier transform infrared spectroscopy (FTIR) was also performed to find the groups of the capping materials which were responsible for the stability of the nanoparticles.","PeriodicalId":372799,"journal":{"name":"2012 IEEE Students' Conference on Electrical, Electronics and Computer Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121305771","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}
