Traditionally, boost converters (BC) are required to operate as an intermediate interface to drive high power loads through available low voltage (LV) sources such as a fuel cell (FC), photovoltaic or battery based energy system. This paper addresses the complementary operation of parallel connected boost converters (PCBC) for high power applications considering wide spectrum of low voltage source conditions. The mutual sharing of load current between parallel connected converters is guaranteed by the appropriate placement of LC based passive equalization filter (LCEF) therefore offloading stress from individual converter and increasing efficiency and reliability drastically. To validate the performance of proposed topology in real-time scenarios, an experimental setup consisting of programmable source, electronic load, boost converters and filter circuit has been synthesized and studied in various operating conditions such as FC energy system based HP and LV application. The experimental results clarifies and validates the necessity of parallel connected converters based power splitting strategy and LC equalization filter topology for high power loads especially with low voltage source conditions.</p></div>","PeriodicalId":11517,"journal":{"name":"Energy Procedia","volume":"162 ","pages":"Pages 349-358"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.egypro.2019.04.036","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74157080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of the equipment needs deep studies to avoid such disturbance. This paper presents a new way in ferroresonance studies, by the use of the Root Cause Analysis (RCA) in a systematic step by step process to discover the true cause of this problem. A fault tree is built to identify all possible causes leading to the unwanted top event, that is the False Trip Analysis (FTA). Among large statistics of disturbances, the probability of occurrence of ferroresonance is stated, and using the most studied causes of this event, the tree of analysis is built till reaching the main disturbance. In each step, well-known possible causes are shown. Then, a barrier or possible solution corresponding to the cause is presented. The new probability of occurrence is then calculated. The obtained result is compared to the initial probability and a set of protection system is proposed. The advantage of this study is the possibility to reduce the occurrence of the ferroresonance by gathering the maximum detailed amount of possible causes and by choosing the best barrier corresponding to the cause.</p></div>","PeriodicalId":11517,"journal":{"name":"Energy Procedia","volume":"162 ","pages":"Pages 306-314"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.egypro.2019.04.032","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77493026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
