Because the switching signals are generated with delaying method traditionally, the dynamic regulation is poor. A novel waveform modulation technique for the staircase inverters is proposed in this paper, which adopts sequential sampling Space Vector Modulation (SVM) technique to generate all the switching signals, therefore the bandwidth of the inverters is enlarged. Based on the analysis of effects on the six basic vectors of each inverter bridge by phase-shifting transformers, a special sample sequence of SVM, which is from lagged bridge to the leading one, is proposed to meet the logic requirements of gating signals. The spectrum of output waveform and the characteristics of this modulation technique are analyzed. Simulation and experiment results prove that this modulation technique can be used to regulate the output of the staircase inverter with excellent output spectrum, and the bandwidth of the inverter is extended, which is helpful for improving the inverter's dynamic performance.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"37 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":"131618935","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}

A cost optimized design of a cascaded filter of a multi-phase converter for an automotive energy back-up system will be shown, that results in small values of the inductances. However, the decreasing inductance values results in increasing current ripples in the first filter stage. The implementation of coupled inductors helps to reduce the current ripples of the single phase currents significantly and achieves a cost optimized design with increased converter efficiency. The influence of tolerances on the ripple cancelation phenomenon in multi-phase converters and coupled inductors on the cascaded filter design will be analyzed. The theoretical predictions are in good correlation with the experimental results obtained from a full-size prototype converter.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"105 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":"126980552","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}

Nowadays the research activity is focused on the development of control strategies that can exploit the degrees of freedom that exist in multiphase machines. As known, a multiphase motor cannot be analyzed using the space vector representation in a single d-q plane, but it is necessary to introduce multiple d-q planes. In this paper the problem of the space vector modulation of multiphase inverters with an odd number of phases is solved introducing the concepts of reciprocal vector and adopting an algorithmic approach, i.e. the information on the inverter configurations, saved in a look-up table, is accessed on the basis of an iterative procedure. The proposed approach, confirmed by experimental tests, allows the full exploitation of the dc input voltage and the simultaneous modulation of voltage space vectors in different d-q planes.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"520 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":"133227724","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}

With this structure, low voltage high frequency ICs and low profile components can be applied in high voltage applications. Flexibility is provided for the cells to work under different voltage supply conditions by simply changing the number of series converters. With the converters operating in continuous conduction mode (CCM), the common duty cycle control approach enables automatic line voltage sharing and output current copying. The approach results in a control-to-output transfer function of the system that is close to that of a single converter for ease of feedback loop design. The modular approach also allows continued operation in the presence of open circuit LED failures. Design considerations and experimental results are presented for a 25 W 3-cell system with 9 Luxeon K2 high brightness LEDs, demonstrating line voltage sharing, output current copying and LED failure response.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"66 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":"133511555","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}

Due to their robustness to parameters variations and external disturbances, sliding mode controllers are widely used for the control of electrical drives. The main interest of using FPGAs to implement such controllers is the very important reduction of the execution time delay. This time reduction derives directly from the possibility offered by FPGAs to design very powerful dedicated architectures. As a result, the quality of the regulated current is quite similar to the one performed by an equivalent analog control. Numerous experimental results are given in order to illustrate the efficiency of FPGA-based solutions to achieve high performance control of electrical drives.","PeriodicalId":200366,"journal":{"name":"2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition","volume":"41 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":"133045872","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}
