The energy management under load variation is investigated. A simulation model of this specific multi-port converter is developed. By parametric analysis, some properties of the circuit are demonstrated. This converter is part of an energy storage system. The operational principle is demonstrated by using a supercapacitor as an energy storage element. The operation in different energy transfer directions is demonstrated.","PeriodicalId":443994,"journal":{"name":"2022 13th National Conference with International Participation (ELECTRONICA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121049325","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 proposed information system is a combination of hardware and software components that enables the users, more precisely farmers and vets, to track the whole process of livestock farming.

The goal of the paper is to evaluate the accuracy of these methodologies and determine whether the obtained results could be used for hand calculations in the early stage of the design of a CMOS circuit. For this purpose, the methodologies are applied for the extraction of the specific current of a NMOS transistor in a 45nm CMOS technology. The obtained results for Is are used to calculate the transfer characteristics of the transistor and are compared with the transfer characteristics obtained with SPICE simulation to verify the accuracy of the methodologies.","PeriodicalId":443994,"journal":{"name":"2022 13th National Conference with International Participation (ELECTRONICA)","volume":"29 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132921594","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}

Paul. Based on the obtained system of two functional equations and two neutral equations for four unknown functions in part 1 of our analysis, we proved that the mixed problem is equivalent to an initial value problem for a functional system on the boundary. The system of functional equations is solved by fixed point method. Commonly, these problems are solved by numerical methods or by Laplace transformation method that is valid only for linear problems. Our results are verified versus real-world example. The method here proposed could be applied for nonlinear boundary conditions too.","PeriodicalId":443994,"journal":{"name":"2022 13th National Conference with International Participation (ELECTRONICA)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125894903","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}
