    The fundamental equations characterising the full-bridge zero-voltage-switched DC-DC convertor are utilised in a nonlinear design-optimisation routine. The design is subject to realistic constraints along with an objective function of minimal total and/or maximum efficiency. The routine is used to study the effects of switching frequency, leakage inductance and load range for zero-voltage switchin... View full abstract»

    A phase-modulated series-parallel resonant convertor is introduced and analysed in the frequency domain using Fourier series techniques. The convertor consists of a class-D phase-modulated series-parallel resonant inverter and a class-D rectifier. Analytical expressions are derived for various parameters of the inverter to study its behaviour. Three types of voltage-driven rectifier are considered... View full abstract»

    A novel and simple DC link voltage boosting circuit is proposed to enhance the performance of inverters for single-phase switched-reluctance motors. It consists of only two additional components to the single-phase switched-reluctance motor inverter, namely a capacitor and a diode. Except for some increase in the voltage rating of the inverter components, no change to the inverter hardware is need... View full abstract»

  • Saturated permeance of identically, doubly-slotted magnetic structures

    Publication Year: 1993, Page(s):323 - 328

    The saturated permeance of the teeth-airgap region in doubly-slotted magnetic structures is expressed as a product of the unsaturated one and its associated permeance saturation factor, each of which depends on only three independent variables. The normalised overlapping width of opposite teeth is introduced as a new independent variable, which makes the reduction of the number of governing parame... View full abstract»

  • Analysis of series-connected wound-rotor self-excited induction generator

    Publication Year: 1993, Page(s):329 - 336

    The paper presents theoretical and experimental investigations for steady-state performance of a three-phase wound-rotor series-connected self-excited induction generator (SCSEIG). This type of generator can be realised by series connection of stator and rotor windings of a slip-ring type induction machine. Self excitation may occur when a suitable capacitor bank is connected across the machine te... View full abstract»

    The first two authors comment on the paper by F. Tosato and S. Quaia (see ibid., vol.,139, no.5, p.443-8, 1992). The authors point out that the idea of the model proposed by Tosato and Quaia is the same as that proposed by themselves in several other papers. There are, however, two differences between the model proposed by Tosato and Quaia and that of the authors regarding the definition of the pa... View full abstract»

  • AC train emergency fuzzy logic control using an event driven approach

    Publication Year: 1993, Page(s):307 - 315
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (716 KB)

    The paper proposes a fast, versatile and easy-to-use technique for control of train despatch schedules in an electrified railway system for improving its performance following an outage of a station transformer. Using the technique of event driven approach and fuzzy logic, it is shown how a set of performance indices which represent the requirements on passengers, headway, regularity, and electric...
