The outer control loop that ensures appropriate loads sharing, is based on the droop control principles with implemented virtual inductance. As the inner control loop a voltage regulation topology using values transformed into Direct-Quadrature (D, Q) synchronous reference frame is implemented. The dynamic and static behavior of whole control system was verified by simulations. Prepared control software based on described strategy was implemented into control systems of the three phase inverters forming a parallel system. The whole parallel system was verified by experimental measurements.","PeriodicalId":165069,"journal":{"name":"2020 ELEKTRO","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116795753","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}

Internet is a part of everyday life in the last years. People visit websites with different devices. Many methods serve to properly display and optimize web content. These methods are constantly being improved to provide convenient viewing of Internet content. We've created our own app based on methods designed to display web content correctly. The app contains an algorithm for identifying the main content of a web page and then extracting text and images from it. The goal of the algorithm is to remove redundant information from the webpage and create a new view that contains only useful information. The document created in this way can be further used in web content viewing applications with minimized data transfer or as direct printing of the main web page content without unnecessary data.","PeriodicalId":165069,"journal":{"name":"2020 ELEKTRO","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121070918","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}

These over-voltages depend on instantaneous energy states of system state variables. A new modified method of instantaneous calculation for state variables is used. It makes possible to specify the values of the state variables at any discrete time instant without having previous values, just initial ones at the beginning of the transient. Based on these values it is possible to estimate the voltage and current stresses of semiconductor elements and to circulate energy inside in power circuit. It is shown that maximal or minimal over-voltages depend on the instants of the transients whose knowledge is presented. Circulating energy makes it possible the correct operation of the power electronic system. Theoretical output results are confirmed by simulation experiments in Matlab/Simulink environment.","PeriodicalId":165069,"journal":{"name":"2020 ELEKTRO","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127111690","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}

Through this analysis it will be possible to follow a final product from the extraction and processing of the necessary raw material, considering all its phases of production, transport, use, cost-effectiveness, maintenance and recycling or until its reintegration into the environment. LCA encompasses risk estimation and environmental impact and, based on International Standards ISO 14040 and ISO 14044, this methodology can be applied at every phase of the product’s life cycle.This scientific paper synthesizes the studies on the following subjects: the increasing importance of the electrical vehicle’s manufactory, the current situation of implementing sustainable development of electric vehicle (EV) components, along with a discussion of neglecting LCA applications, as a premise for balancing the negative impact of a product during its long-life cycle for the environment. Thus, the purpose of this scientific article is a review of the most relevant scientific articles written based on a life cycle impact assessment approach of EVs or its components (battery, electric motor, etc.). It will be discussed in depth the importance of an LCA analysis in each step of its implementation, the related main topics in the previous analyses, as well as the interpretation of the results obtained.","PeriodicalId":165069,"journal":{"name":"2020 ELEKTRO","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115186973","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}
