The primary focus of this paper is to describe the design of the converter and experimentally evaluate its performance (steady-state efficiency and load-sharing and dynamic performance) at high coolant temperatures (¿ 105 °C). Further, the key components of the converter losses at high temperature are identified. Because VJFET switching losses are the key component of the converter loss, the effectiveness of a soft-switching scheme that mitigates these losses is also evaluated.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130106919","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 make a more accurate fluorescent lamp model at different dimming levels necessary at low operating frequency. This paper presents a new method that considers the effect of tube temperature at different dimming levels in the process of the analysis of the fluorescent lamp model. The model is verified favorably by the comparison between the simulation results and experimental results. It's clear that after the effect of tube temperature at different dimming levels is considered, the model becomes more accurate and reliable than before. This model can be used to design dimmable magnetic ballast. Hence, the proposed model shows a good degree of accuracy for a large dimming range at different operating frequencies.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126999166","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}

Existing multiphase buck controller and buck driver can be directly used in the proposed converter. The advantages of the proposed converter are: 1) duty cycle extension; 2) significant switching losses reduction due to ZVS of all the control MOSFETs; 3) reduced reverse recovery loss and lower voltage rating synchronous rectifier (SR) MOSFET with lower RDS(on); 4) high drive voltage to reduce RDS(on) and the conduction losses of SRs due to gate energy recovery capability; 5) reduced body diode conduction and no external drive IC chips with dead time control needed for SRs due to the inherent current source gate drive circuit structure. The experimental results verify the principle of operation and significant efficiency improvement. At 12V input, 1.3V output and 1MHz switching frequency, the proposed VRM improves the efficiency from 80.7% using the buck converter to 83.6% at 50A, and from 77.9% using the buck converter to 80.5% at 60A.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"50 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120902934","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}

Matrix converter is interfaced with three phase AC voltage source. And the AC source makes three different level virtual DC-link voltages. In this paper, a generalized PWM method is proposed to use these three virtual DC-link voltages. In the case of using higher two line to line voltage as virtual DC-link, the proposed method is exactly identical with the conventional SVPWM method. Moreover, the proposed method is able to select the virtual DC-link according to the PWM purposes and/or load condition. Selecting the virtual DC-link which is adjacent to the output voltage reference, the output current switching ripple can be reduced. The feasibility of the proposed PWM method is verified by a computer simulation and experimental results. The output voltage and current of the proposed method can be identical with that of the conventional SVPWM method. Moreover, a new switching sequence to reduce the output current switching ripple can be easily adopted. Compared with the output current of the conventional PWM method, the harmonic characteristics of the proposed method can be significantly improved.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122595649","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}
