These kinds of converters have the advantages of simple circuit topology, bidirectional flows, zero-voltage-switching (ZVS), high efficiency, and high power density. The turned-on ZVS for all MOSFETs is achieved by the negative offset of the inductor current at the beginning and the end of each switching period. To do this, the converter requires a complex switching strategy which is preferred to be implemented by the digital signal processing (DSP). This paper presents the digital implementation of the switching pattern to ensure the ZVS condition for such converter. A 5kW prototype is performed to verify the capability of such control scheme.","PeriodicalId":356367,"journal":{"name":"2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130289550","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 buck-boost converter could be operated in all conversion modes including step-up, step-down, and step-up-down, with variable battery voltages input to the HPLDD. Moreover, the feedback controllers composed of a voltage-loop controller (VLC) and a current-loop controller (CLC) to control the BBC's output voltage and current to drive high-power laser diodes (HPLDs). In the start-up phase, when the BBC output side is operated from the constant-voltage mode and changed to the constant-current mode, a current overshoot occurs, which can damage the high-power laser diodes. This paper proposed a control method, the proportional-switching-proportional-integral control technology, can be used to the CLC to reduce the start-up current overshoot.","PeriodicalId":356367,"journal":{"name":"2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114748831","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 growth of data produced via IoT has played a major role on the big data landscape. The paper is concerned with respect to the Big Data key-value pairs from different database types using the latest version of Elasticsearch 6.0 and classic relational database as MySQL 5.5. This stands for the crucial topics since many databases are used these days and it is difficult to choose the right database for specific scenario. The correct choice for specific scenario is very important in e-applications or communication systems, because it is supposed to save a lot of money and effort. This work aims at comparing and testing Elasticsearch and MySQL DB (Database) with related frameworks e.g., Spring Data. This particular comparison is done via searching values in larger key-value datasets. At this point, it is very important to know which database to choose in this scenario, because it is often used in e-applications e.g., when e-application wants to store session ID and user time spent in e-app. Simulation scenarios in this paper were created using real data sets provided by IBM internal e-learning app. Based on performed tests, authors provide the community with a suitable way of storing data.","PeriodicalId":356367,"journal":{"name":"2018 3rd International Conference on Intelligent Green Building and Smart Grid (IGBSG)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114420869","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}

Droop control has been adopted in micro-grid to automatically share power and regulate output voltage of parallel voltage-controlled inverters (VCIs) in micro-grids.
