    초록

    Component-based Distributed Railway Interlocking System (CBDRIS) was presented recently. It is expected to reduce the development time and improve the reliability of railway interlocking systems. All interlocking devices in CBDRIS are at the same layer and there is no centralized interlocking computer. In this paper the CBDRIS is modeled with Petri Nets. We model CBDRIS in three layers: functional modules, device components which consist of functional modules, and the whole interlocking system which comprises of the device components. Considering route conflict and device conflict probabilities are key factors to route reservation success, we analyze the relations between the two conflict probabilities and route reservation success probability with the proposed approach and based on the modeling results, which is useful for system design and development.

    초록

    This paper presents a Finite Element Analysis of a Permanent Magnet Linear Synchronous Motor. The aim is to obtain an accurate estimation of the detent force without oversize computation. First, some usual techniques dedicated to the calculation of the forces in electromagnetic devices, such as the Virtual Work Method and the Maxwell Stress Tensor, are described. Some keypoints of the meshing method using a commercial FEM software are presented and used in order to improve the thrust computations. After that, the topology and features of the studied motor are described to highlight specific problems of the modelling process. In the 2D FEM case, new meshing techniques are proposed, according to the force calculations. The FEM results obtained from the different methods are analysed and compared with the experimental ones. Second, using FEM results, a study of the independence of the cogging and the end-effect forces is presented. Particularly, an original approach is suggested in order to compute the cogging force only, using the same mesh for each motion step. Then, the PMLSM geometry is adapted to calculate the end-effect forces only.

  8. [해외논문]   Three-Level Current-Source PWM Inverter with No Isolated Switching Devices for Photovoltaic Conditioner

    電氣學會論文誌. The Transactions of the Institute of Electrical Engineers of Japan. D, A publication of industry applications society. D, 産業應用 v.129 no.5 ,pp. 505 - 510 , 2009 , 0913-6339 ,

    초록

    This paper presents a new configuration of a three-level current-source PWM inverter (CSI) with a full common-source or common-emitter topology in terms of all transistor switching devices. Using this new configuration, the number of gate or base drive power supplies can dramatically be reduced to only a single instead of use of several isolated power supplies or conventional bootstrap circuits. As a result, bulky, heavy and expensive transformers and capacitors in the drive circuits are eliminated. In addition, the proposed configuration is capable to be operated at a higher switching frequency and a higher voltage without violent potential changes because of its common-source or common-emitter topology. Design and operation principle of the new circuit are investigated and analyzed using computer simulations. Finally, effectiveness of the circuit is experimentally verified by using a laboratory prototype set up. The simulation and the experimental results show that the circuit works properly to generate a three-level output current waveform, which proves feasibility of the proposed approach.
