In fact, the maximum temperature rise of component must be kept under a limit that heat dissipation cannot destroy the device materials. Therefore thermal modelling has to be taken in design optimisation of the components. We propose, in this paper, two analytical thermal models of free convection and radiation that can be applied to planar magnetic components. The models are verified by experimental tests, advantages and weakness of each model are analyzed to find out an appropriate one using in optimization tools.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"187 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124930725","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 new converter structure is designed in such a way that, the modularity is available not only for voltage but also for current ratings, using the available devices. The new converter will be applicable for a wide range of medium voltage applications and using its modularity it also can be scaled up for high voltage applications. The proposed-converter control is described and the overall operation is explained through simulation. A simple active-reactive power control is utilized for the converter control. It has been highlighted, through simulation, that the proposed converter has a high degree of design flexibility introduced by its high number of redundant switching states. These redundancies are implemented for controlling the capacitor voltages of the converter modules. More importantly, they provide the converter with a DC and AC sides fault-handling capability; a function that is essential for an MV converter. It is explicitly shown that the converter can provide ancillary services to the grid during DC faults.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125434380","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 respect to the classical linear voltage control the SM gives rise to a wider regulation band but, unfortunately, in presence of a fast irradiance variation the SM conditions could be violated producing a divergence of the operating point with respect to the desired one. In order to prevent such a drawback, an appropriate voltage compensation loop is used to interface the Sliding Mode with the Maximum Power Point Tracking algorithm. Simulation results confirm the goodness of the proposed algorithm. The proposed approach is currently patent pending.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125570594","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 fault containment mechanisms, which are based on the time-triggered Network-on-a-Chip (NoC) of a reconfigurable MPSoC. Each component accesses this NoC via a communication interface that acts as a guardian of the component behavior in the time and value domain. The knowledge about the permitted behavior of a component is written into the communication interfaces by a trusted resource manager. We perform an evaluation of these fault containment capabilities using fault injection experiments. The experiments provide evidence that a faulty component cannot affect the timing or integrity of messages exchanged by other components.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126317087","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}

Accuracy of these appliances substantially affects the resulting accuracy of the measurement. An important parameter which affects ICT or IVT accuracy is their burden. Therefore the calibration of instrument transformers (IT) must be performed at a desired value of the burden. It usually varies in the range (1 up to 75) VA. ICT burdens less than 5 VA are usually real or they have the inductive power factor 0.8 for greater values. IVT burdens have usually inductive power factor 0.8. A precise adjusting of the burden is important to achieve required IT calibration accuracy. Burden calibration is a necessary part of the calibration process. Procedures for burden calibration used at CMI are described in the paper. There is described a procedure using a standard transformer test set and also procedures with PC controlled measuring systems.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129614699","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}
