This leads to a smaller output inductance required for the same inductor current ripple. Therefore, the dynamic response will be faster than that of the conventional Buck converter. In this paper, to further improve the dynamic performance, the current feed-forward control scheme is applied to the TL-Buck converter. To validate the effectiveness of the proposed topology and controller, both Matlab/Simulink based simulation and experimental results are presented. The main advantages of the proposed approach include faster dynamic response, simple topology configuration, and simple controller implementation.","PeriodicalId":161915,"journal":{"name":"2010 IEEE Energy Conversion Congress and Exposition","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128662244","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}

Instead of directly sensing the inductor current, an inductor current ramp estimator with the drift compensation is proposed as adding a virtual ESR ripple to the output voltage ripple. Only the input and output voltages are required to be sampled for the current ramp estimation. Hence the sampling-rate requirements for the analog-to-digital converters (ADCs) in the digital implementations are not critical. The limit-cycle oscillations due to the sampling effects can be improved by using the estimated current ramp with compared to the direct current sampling. Besides, the small-signal modeling of the digital enhanced V2 control architecture can provide the design guideline for choosing the current feedback gains. The effectiveness of the proposed control architecture and the current ramp estimator has been verified with simulation and experimental results.","PeriodicalId":161915,"journal":{"name":"2010 IEEE Energy Conversion Congress and Exposition","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128683988","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}

Under such operating scenario, the distributed generators within microgrid should form a high quality voltage supply for the load to sustain its normal operation. Power converters, the interface of renewable sources and energy storage systems, are an important component of microgrids. The size and the number of the power converters required will depend on the fluctuating power flow within the microgrid. In this paper, we propose a hybrid control architecture to balance the power shared among the multiple interface inverters and optimize the system operating efficiency. Simulation and real time test results are provided to validate the proposed hybrid control scheme.","PeriodicalId":161915,"journal":{"name":"2010 IEEE Energy Conversion Congress and Exposition","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129480807","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 structure of the generator system is such that the three-phase brushless dc generator provides power to an uncontrolled rectifier. The rectifier output is filtered by electrolytic capacitors. The uncontrolled dc output voltage feeds a dc-dc converter to regulate the output voltage. The electronic units, the uncontrolled rectifier and the dc-dc converter, are individual EMI noise sources. The approach taken deals with the individual noise sources separately and suppresses the noise as close to each source as possible. The EMC measurements and impedance measurements are done without any noise reduction effort to characterize the system. The characterization of the different EMC filter types is presented and simulated in Matlab. Using the measured system characteristics, and the characteristics of the actual filter types, noise reduction techniques have been implemented either through most appropriate EMC filters or through snubber networks. Tests and measurements are performed with each individual component added. The method, which approaches each individual system separately, provides compact and cheap filter solutions to meet the EMC requirements.","PeriodicalId":161915,"journal":{"name":"2010 IEEE Energy Conversion Congress and Exposition","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130376724","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}

However, by installing the ballast inside the lamp fixture, the ambient temperature for the ballast will be higher, and combined with the reduced size, the thermal condition for the integrated ballast will be much harsher. Therefore the detail thermal analysis and proper management is a must for the high power density ballast design. In this paper, a thermal simulation model of the integrated ballast is developed with experimental calibration, with which the thermal performance of the ballast within a plastic fixture is studied. The thermal management methods to reduce the peak temperature are also investigated and discussed based on the model.
