In order to achieve high efficiency, the choice of the component plays a major role. At the same time, such systems require high performance in terms of faster switching, high-power, and high-temperature operation capability. Converters with conventional silicon-based power switching devices may not accomplish all these requirements effectively. This paper presents the design of a single-ended primary inductance converter (SEPIC) using silicon carbide (SiC) and conventional silicon power switching devices to compare the performance in terms of the efficiency. The designed converter was first validated in PSIM simulation software to assess the effectiveness of using SiC power devices to charge a 48 V battery from a 250 Wp PV panel with a voltage of 30.7 V. Furthermore, a hardware prototype of the converter was developed and tested on a resistive load. The use of SiC-based switches increased the efficiency of the SEPIC converter by 3.6% at full load and at a switching frequency of 100 kHz.","PeriodicalId":375493,"journal":{"name":"2017 Brazilian Power Electronics Conference (COBEP)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124531851","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}

In the literature, active islanding detection methods are preferentially used because they have smaller non-detection zones compared to passive techniques. However, on these methods, continuous disturbances are injected on DG's control and degrade the power quality provided by the electronic converter. In this context, an active islanding detection technique frequency-based with positive feedback and fixed gain is discussed, based on the classical techniques. This research aims to investigate the method's performance in relation to the detection time and the injection of disturbances in the DG's control system. From this analysis, an anti-islanding technique is developed to guarantee similar efficiency to the traditional method in cases of small-power flow through the grid, even as minimize disturbances in different points of the plant operation. This technique is based on the calculation of the variable gain on the positive feedback, that is inversely proportional to the active power deviation delivered or absorbed from the grid.","PeriodicalId":375493,"journal":{"name":"2017 Brazilian Power Electronics Conference (COBEP)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117226103","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 approach employs the complete steady state model of the motor and aims at the calculation of efficiency, power factor, current, torque and other quantities at any load. The methodology consists of a first stage, in which a search space for the genetic algorithm is determined, and a second stage in which the circuit parameters and auxiliary slip values are determined. Three different types of motors were investigated, with pole number and power varying from 2 to 6 and from 10 hp to 100 hp, respectively. The accuracy is verified based on deviation from catalog data, reference parameter values obtained experimentally and experimental data. Results indicate that the proposed methodology is capable of finding parameter values which fit the catalog data, although the inaccuracy of these data causes deviation from reference parameter values. The used heuristics is shown to reduce the deviation of less sensitive parameters.","PeriodicalId":375493,"journal":{"name":"2017 Brazilian Power Electronics Conference (COBEP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130713088","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}
