The proposed converter uses two transformers to reduce the current stress on the power components to reduce the conduction loss and improve the efficiency. When the proposed converter is operated in the step-up mode, the voltage across switches is clamped at the input voltage, and the leakage energy is recycled to the voltage source. When the proposed converter is operated in the step-down mode, the voltage of switches is clamped at the input voltage, and the leakage energy is recycled to the clamping capacitor or the voltage source. As the proposed converter is based on flyback converter, it is characterized with simple structure. Since the leakage inductance energy is recycled, the conversion efficiency is improved compared to conventional flyback converter. Finally, a laboratory prototype circuit with 200 V/24 V and output power 500 W is implemented to verify the feasibility of the proposed converter. The highest efficiency in the step-up and step-down stage is 92.3% and 95.5% respectively.","PeriodicalId":217916,"journal":{"name":"2017 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123728533","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 comprehensive precharging sequence is introduced for the active front-end rectifier of the SST to limit the inrush current during the start-up process to its nominal current. The proposed precharging algorithm consists of two phases, passive and active precharging. The precharging resistor limits the current during the passive precharging, while a ramp increase of the voltage reference is used in the controller during the active precharging to prevent large inrush currents. Additionally, a feedforward voltage compensator is added to the voltage reference of the controller to improve the dynamic response at the beginning of the active precharging. The proposed algorithm is detailed and simulation results on a 4-kW active front-end converter are presented to validate its performance. The simulation results under various operation conditions show the ability of the proposed algorithm to limit the converter current to its nominal value during the precharging as well as to control the dc-link voltage under different load changes.","PeriodicalId":217916,"journal":{"name":"2017 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125582562","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}

As a potential solution, a Dual rotor Darrieus Turbine (DD) with secondary rotor in addition to the primary rotor has been proposed to improve the self-starting characteristics and to enhance the low wind speed performance. The current study experimentally evaluates the proposed rotor with two set of blades as a possible means of achieving higher static torque and thus promoting self-starting capability. Albeit, the design parameters for the secondary rotor such as solidity, appropriate airfoil, secondary rotor diameter, secondary rotor offset with respect to primary rotor requires extensive optimization, the current preliminary study is focused on the feasibility check of the DD turbine. Power coefficient, dynamic and static torque coefficient are obtained through wind tunnel test and compared with Conventional Darrieus (CD) turbine (only with primary rotor). The results indicate the novel dual rotor do improve the self-starting capability at the expense of reduced power performance.","PeriodicalId":217916,"journal":{"name":"2017 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116164059","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}

Few of the major challenges in wind industry is the component complexity and material reliability. Thus, there is a need of determining alternative and more efficient manufacturing method. Additive Manufacturing (AM) is a process which enables layer-wise fabrication of complex parts directly from CAD files without part-specific tooling. Additive manufacturing increases design freedom for building complex part geometries that cannot be made by traditional manufacturing methods. The ability to build customized integrated parts with less material wastage is desirable. The main aim of this paper is to discuss about the possibilities of using AM in spare parts production in wind Industry. To justify the compatibility of AM, there is a need to determine the loads acting on the wind turbine components. Hence, load analysis of AOC 50 kW reference wind turbine was simulated through FAST and Rainflow counting algorithm. The results from the simulations were used to compare the experimental fatigue data of AM material with one of commonly used wind turbine material.","PeriodicalId":217916,"journal":{"name":"2017 Asian Conference on Energy, Power and Transportation Electrification (ACEPT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114575087","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}
