    In this paper, we introduce a new ATM switch architecture. Buffer access speeds of the proposed architecture match the port speeds, and the buffer acts, in effect, as a multiport memory. The input buffers are implemented as a group of parallel shift registers. This approach overcomes the head-of-the-line (HOL) and low-throughput problems of input buffers. Shift-register buffers allow operating spe... View full abstract»

  • Flashover performance of ice-covered insulators

    The presence of ice on the surface of insulators is sometimes the cause of severe problems in power networks. In fact, the presence of ice reduces the electrical performance of insulators in ways that can, in some circumstances, lead to flashover, resulting in power outages. The maximum withstand voltage of ice-covered insulators is distinctly inferior to that of clean insulators. The electrical p... View full abstract»

  • A DC/AC converter with input resonant circuit and single-phase inverter

    Publication Year: 1997, Page(s):111 - 118

    This paper presents a new dc/ac single-phase converter. By equipping the inverter input with a resonant circuit, the switching loss in the semiconductor devices has been reduced and the electromagnetic interference problem has been rendered less severe, because the resonant voltage pulses have lower dv/dt. Moreover, due to the resonant-circuit presence, a good sinusoidal voltage is applied to the ... View full abstract»

  • Dynamic analysis of LCC-type parallel resonant converter operating in discontinuous current mode

    Publication Year: 1997, Page(s):119 - 129
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5094 KB)

    A discrete time-domain model for the LCC-type parallel resonant converter, operating in discontinuous current mode (DCM), is derived. This model, which makes use of some practical approximations, simplifies the calculations, reduces the computer simulation time and is adequate to predict some of the basic design constraints (peak component stresses, etc.) which are governed by the dynamics of the ...

  • Transient stability assessment of power systems by a new estimating neural network

    Publication Year: 1997, Page(s):131 - 137
    Cited by:  Papers (2)

    The problem of transient stability assessment and its difficulties are explained. An expert system using a neural network that is appropriate for determination of transient stability of power systems is discussed in the paper. This neural network is applied to determine the critical clearing times in a disturbed power system. Applications of this method and its advantages and disadvantages are dis... View full abstract»
