In this paper we describe the system architecture with ZigBee as the communication medium, followed by an experimental setup to demonstrate the iEMS with ZigBee communication. Our future work is to measure delay, throughput, received signal strength etc. to characterize the communication link and quantify its effect on iEMS performance.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"15 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":"123870602","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 converter presented utilizes a new variable frequency interleaving approach which allows for each module to operate in an interleaved position while allowing for tolerance in inductance and snubber capacitor values. The variable frequency interleaved operation paired with high-efficiency soft-switching, a high-density inductor design, and optimal packaging results in a very high power-density converter. The 25 kW per module prototype converter exhibited power density greater than 8 kW/L, and peak efficiency over 97%, while operating with 100°C coolant.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"22 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":"121566436","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 the paper a detailed comparison of the two mostly used control strategies for the HEVs is presented. This will provide a fair idea with regards to selection of the control strategy, based on the fuel economy, emissions, acceleration and battery performance of the parallel HEV.

The electric energy of PHEVs is charged mainly during nighttime when the electricity price is low. Therefore, we have proposed a charging power control of PHEVs to compensate the Load Frequency Control (LFC) capacity in the nighttime. In this study, we propose a control method based on Area Control Error (ACE) and frequency characteristic of PHEV KPHEV, which is a change in charging power divided by a change in frequency. ACE is a required adjustment in generation to keep the balance of supply-and-demand; hence, we can also keep the balance by adjusting the demand as much as ACE. LFC signal fLFC calculated by the following equation fLFC = −ACE/ KPHEV is dispersed to all PHEVs; then, PHEVs control the charging power on the basis of fLFC. We evaluated the proposed control method by using an interconnected 2-area model and obtained the following results. Charging power control based on the proposed method can effectively suppress tie-line flow deviation and frequency deviation, and it could substitute for LFC capacity.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"25 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":"130871143","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}

This paper presents a three-phase induction motor drive system with an active IGBT rectifier, i.e. an Active Front End (AFE). The AFE converts the AC line input into a controlled DC-link voltage which is then used as input into a three-phase IM drive, based on an IGBT converter. A reconfigurable IM drive, i.e. the inverter, is controlled by the conventional PWM and space vector PWM based methods. This paper investigates the influences of the DC-link variations on the IM drive under each of these modulation strategies. A simulated drive is verified via an experimental test bed, and is then used to further study more extreme DC-Link fluctuations; specifically, variations 10 percent above and below the experimental value of 670 V. Phase current and voltage THD and spectra will be calculated to evaluate the fluctuations influence on performance characteristics.
