In this paper, a novel distributed control system is presented for a modular wind turbine drive with 12 parallel converter modules, where each module has a local control platform and two central control units are used, one active and one redundant unit. A comparison is done of ring versus star network topologies, and it is concluded that the star topology has the advantages of lower latency, higher bandwidth, and better synchronization and the drawbacks of a complex central controller and lower scalability. Analysis is done for fault-tolerant, synchronized operation with a redundant star network topology using 100BASE-TX Ethernet for communications. Furthermore, small custom Ethernet data packets transmitted at regular intervals are used which provides benefits of ensured data integrity, low signal latency, and simple synchronization. Experimental results demonstrate ca. 20 ns synchronization precision, and interruption-free fault tolerance.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"65 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88815796","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 CEIs can be implemented as single-phase or three-phase ones; in this paper, feasible single- and three-phase topologies are introduced and their losses are calculated using nine different power switches. Three commercially available IGBT, MOSFET, and SiC MOSFET power switches are selected for comparison. In this application, a galvanic isolation between the DC network and the customer is required. The isolation is implemented by using an isolating DC/DC converter at the CEI supply, and therefore, the input voltage of the CEI can be different from the DC network voltage. In this paper, the effect of the supply voltage level on the losses of the CEI is calculated for the nine power transistors in single- and three-phase topologies.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"5 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88822685","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}

For aerospace applications, electrical machines providing high torque density are paramount for the viability of direct-drive electrical propulsion of aircraft. Besides low-weight and high torque capability, a candidate solution should also be inherently fault tolerant for it to be used in aerospace. For these reasons a first solution based on Flux-Switching Permanent Magnet (FSPM) machines for an exemplary application of a helicopter main rotor drive was investigated, since these machines have shown high torque-to-weight ratios and high efficiency during research in the last decade. Despite this, the task of designing a machine appropriate for this application goes beyond the electromagnetic design and into the area of mechanical design much deeper than for traditional designs: The lightweight nature of such an iron-based machine makes the design of support structures and airgap control challenging and requires unconventional approaches. This paper presents the main design steps and first experimental results for such a machine.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"16 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90707549","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}

Low switching energies of the applied SiC MOSFETs and Schottky diodes offer operation at high switching frequency. Together with suitable phase-shift of the control signals this leads to input/output current frequency multiplication up to 0.5MHz. Such a high frequencies and cancellation of the current ripples result in a significant reduction of the passive components, especially input inductors. The paper contains discussion of the converter operation and special solution the MOSFET gate drivers with CPLD logic. A design study regarding SiC semiconductors, inductors and cooling system, is also provided. Discussed issues are illustrated by simulation and experimental results.
