Under normal mode of operation, the high side and low side switches of the bridge converters conduct on alternate half cycles. During the commutation if the conduction states overlap the source will be short circuited, destroying the switches. A switching and a linear circuit based schemes have discussed and compared for their relative advantages and disadvantages. Simulation waveforms for the switch and load currents under different operating conditions have been included.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114975906","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 offshore wind farms have also been continuing its growth rapidly due to much better wind conditions like onshore wind farms. The studied system here is a variable speed wind generation system based on Doubly Fed Induction Generator (DFIG). In this topology, stator side converter and rotor side converter is used to implement the DFIG control to achieve wind power conversion. Here, a maximum power control strategy is incorporated with the DFIG, whereby the produced power serves as the active power reference for the DFIG. Stator flux oriented vector control is applied to decouple the control of active and reactive power generated by the DFIG based wind turbine. A DC/DC boost converter is used for DFIG system to DC grid connection. This system represents transferring offshore wind power to the terrestrial ac grid through the High Voltage DC (HVDC) network. The details of the control strategy and system simulation results in Simulink are presented in the paper.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126476357","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}

Since then black outs of power systems have become common. In an interconnected system, the loss of generation in one area can be replaced by generation from other areas. Thus, several systems interconnected can survive contingencies that the individual systems could not. Thus one benefit of interconnected power systems is the potential for increased reliability.

RQA method quantifies the regularity/complexity signals and CRQA method quantifies the similarities between the two signals. The CRQA analysis of EEG is carried out for signals between the channels from different lobes. These two measures are combined in a feature space.

In this paper a four switch three phase (b-4) topology for the grid connected application in an effort to reduce the cost of the inverter is investigated. This topology warrants higher voltage ratings of the semiconductor devices used and the dc-link split capacitors used with respect to a conventional six switch three phase b-6 topology inverter for a specific set of grid voltages. In this paper, application of four power semiconductor switch based three phase inverter is proposed for renewable energy based three phase micro grid interconnection. The b-4 of three phase inverter topology is studied to make the commercial micro grid system to be cost effective and hardware optimized. Switching of four switches is controlled by a simple Sinusoidal Pulse Width Modulation is used to control the switching of the four switches. Main advantage of this converter is that it needs only four switches. Due to the reduction in number of switches system is less costlier and also the complexity in associated with gating and control circuitry is reduced.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130123407","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 presence of noise halo or rare patch effect in non local means denoised image occurs as a result of large variance between pixel values near the edges. This large variance is reduced by deliberately adding a small amount of blur near the edges before applying non-local means denoising and then filtering by Weiner filter reduces the noise halo effect in the resulting denoised image.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125095804","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}
