Abstract
This letter proposes a novel modular commutation converter with high-overload capability for high-voltage dc transmission. The combination of single-switching-device modules (SDMs) and high-switching SDMs exploits the soft-switching characteristics of the topology and the high surge-current capability of integrated gate-commutated thyristors, enabling the converter to achieve short-term high-overload capability at reduced cost and volume. The topology, operating principle, and device characteristics are presented in detail. A megawatt-level engineering prototype is developed, and experimental results demonstrate the feasibility of the proposal.
期刊介绍：
The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
