This student event is a chance for several teams from all over the world to compete against one another in a real world engineering environment. The growth of the competition has been very evident over the three year period—with 28 teams participating in 2009. This growth has sparked a passion at Illinois Institute of Technology (IIT) for designing, building, and racing hybrid electric vehicles (HEV). Involvement in the competition has allowed for IIT to teach its students this advanced technology not only in the class room, but also with real world applications where students have been able to take the ideas and methods they have learned and implement them in this one of a kind competition. The WISER team at IIT fielded two student-designed hybrid electric vehicles of differing drive trains for the 2009 competition. These vehicles are cutting edge on many levels including lithium polymer and lithium phosphorus batteries, ultra-capacitors, a continuously variable transmission, and an electronic differential.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130737461","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}

There are many control strategies that have been developed and presented. Most of them are expansions of hybrid electric vehicle control strategies and do not maximize the true potential the PHEV offers as a result of its ability to operate in electric only mode over a significant distance. In this paper, state-of-the-art control strategies are reviewed and classified in detail. PHEV controllers operate mostly on either a rule based or optimization based algorithm with each having its own advantages and disadvantages. An overview of the controllers and an analysis on which strategy is more suitable to maximize PHEV performance in different drive cycle conditions are discussed as well.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134224585","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 CM voltage at the motor terminals, creating a shaft voltage through the motor air-gap with a possible arising of bearing current, can endanger the motor reliability and reduce its lifetime. Therefore the CM voltage filtering is desirable. A detailed description of a common mode active filter (CMAF) is reported. An analysis of the motor CM voltage and current on the motor ground connection, before and after the introduction of the CMAF, is performed. Furthermore the electromagnetic interference (EMI) towards the vehicle DC power supply line is investigated. All phenomena are studied both in simulation and experimentally. The simulated results are obtained developing a high frequency circuit model of the drive system, including the CMAF, implemented in PSpice simulator. In order to accurately perform the experimental tests, a new dedicated high voltage dual DC line impedance stabilization network (LISN) is designed and set-up, on purpose. The CMAF is found to be an effective solutions for the increase of the motor reliability and of the drive electromagnetic compatibility. Moreover the CMAF does not worsen the EMI towards the DC supply line. Therefore its presence do not imply the need for additional filters, respect to the case where no CMAF is used. Simulated results are in good agreement with the experimental ones, confirming the validity of the proposed modeling of the drive system.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133187457","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}
