    The edge-based finite-element method (edge elements) is used to obtain a numerical solution for the radiated emissions and crosstalk voltages on printed circuit boards (PCBs). Both shielded and open PCBs, over a wide frequency range, are analyzed and compared. The novelty of the approach presented in this paper lies in its use of the edge elements for open boundary problems. The method of analysis is two-dimensional, and has the expected advantages of edge elements; namely, it does not produce spurious solutions and it models sharp points and edges without any need for special singular trial functions. Furthermore, the matrix obtained is sparse and symmetric, and the solution can be obtained directly, with no need for matrix inversion. View full abstract»

    A systematic method for the realization of complex digital filters based on the concept of the generalized-immittance converter is presented. The method is simple to apply and can be used to realize arbitrary one-dimensional and multidimensional complex digital filters. The method is then used to realize a fourth-order Chebyshev filter, and the sensitivity performance of the filter is compared with that of other known low-sensitivity structures. View full abstract»

  • High-performance soft-commutated converter for solar energy conversion

    In this paper, the authors present a detailed study and analysis of a series resonant converter topology operating in quasi-resonant mode. The dc-to-ac converter is used to convert the solar energy obtained from a photovoltaic field into an ac current. Theoretical study based on the state-plane method is completed and sets of static characteristics curves for all operating modes are obtained. A general design methodology is elaborated which permits the determination of the constraints on the semiconductors and reactive components. Finally, a performance analysis of the converter feeding different types of loads (utility, linear and nonlinear loads), and a harmonic analysis of different waveforms based on simulation and experimental results are presented.

  • Design and simulation of a high-voltage direct-current source

    This paper presents the design and simulation results of a 70 kV, 60 A, high-voltage direct-current source. The proposed solution consists of 96 three-phase bridges connected in series in a 36-pulse arrangement and fed by a cascade of three dry-type transformers. Simulation results obtained using the EMTP software (Electro Magnetic Transient Program) confirm the feasibility of the design and the theoretical estimates of the dc voltage ripple and the ac line current harmonics.

  • High-speed area-efficient inner-product processor

    In this paper, a novel technique for the design of a high-speed word-level two's complement fixed-point inner-product processor is described. The new scheme offers a highly regular structure ideally suited for VLSI implementation. A comparison in terms of speed and area between the proposed scheme and two other inner-product processors is presented. A reduction in the computation time ranging from 20% to 50% compared with other schemes has been achieved using the proposed processor, without a significant increase in the required area.

  • Deadlock-preventing routing in hypercycles

    Hypercycles make up a class of multidimensional graphs obtained by allowing each dimension to incorporate more than two elements and a cyclic interconnection. Hypercycles offer simple routing and the ability, given a fixed degree, to choose among a number of graphs of varying size. These graphs can be used in the design of interconnection networks for distributed systems tailored specifically to the topology of a particular application. We present and prove a deadlock-preventing routing strategy for a subset of hypercycles, and a VLSI hypercycle router component which implements the deadlock-preventing routing. View full abstract»
