    The aspects of design associated with the current source inverter (CSI) induction motor drive are reviewed and a systematic procedure for the optimum design of the drive is presented. The optimisation is carried out using the sequential unconstrained minimisation technique. The study takes into account the inherent slow commutation process, the torque pulsation and the peak voltage stress in the C... View full abstract»

    This work presents a new rectifier connected in the bridge configuration, which uses six bidirectional switches to connect the 3-phase source to the load. Each bidirectional switch comprises two power MOSFET transistors working in the switching mode. A simple pulse-width modulation strategy is developed using the ficticious source concept. The convertor works at a high switching frequency and for ... View full abstract»

  • Bilateral DC to AC convertor using a high frequency link

    Publication Year: 1987, Page(s):15 - 24
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1257 KB)

    The paper describes a bilateral high frequency DC/AC convertor for uninterrupted power supply applications. The proposed convertor can also function as a battery charger without any additional power circuit components. Moreover, this convertor provides ohmic isolation between the DC source and the load at high switching frequencies for the forward and reverse power flow modes of operation. Consequ...

  • Harmonic minimisation in microprocessor controlled current fed PWM inverter drives

    Publication Year: 1987, Page(s):25 - 41
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2404 KB)

    New microprocessor-based pulse-width modulation (PWM) control techniques are presented for the current fed inverter (CFI) drive, which minimise the harmonic torque and speed-ripple effects normally associated with low-speed quasi-square-wave operations of CFI drives. It is shown how high-pulse number PWM harmonic elimination current strategies can be developed and used to eliminate substantially g... View full abstract»

  • Costing energy savings for a dual-mode motor

    Publication Year: 1987, Page(s):42 - 46
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (605 KB)

    An analysis is presented of energy savings realised for a fixed speed induction motor by using a dual-mode design. This uses a nonstandard divided stator winding allowing two alternative modes of connection of the winding sections, to be selected according to loading. Control is automatic using microprocessor and thyristor switches but alternatively manual control may be used. Power losses are red... View full abstract»

  • Electrical design of air-cored synchronous generators using superconducting field and armature windings

    Publication Year: 1987, Page(s):47 - 52
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (659 KB)

    The emergence of superconducting wires able to support 50 Hz fields and current variations allows AC machines with superconducting coils both field and armature windings to be studied. The electrical design of a 500 kW generator is presented, using a no-quench criterion for the SC wire, even during transients. The results are good enough to predict the construction of a prototype AC generator. View full abstract»

  • Single-phase switched reluctance motors

    Publication Year: 1987, Page(s):53 - 56
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (408 KB)

    The paper describes the design features and performance of single-phase switched reluctance motors for low-power variable-speed drives. The main advantages of these motors lie in their simple robust construction and low manufacturing cost. Experimental results from two prototypes are given, showing satisfactory performance.

  • Static frequency convertor for supplying an asynchronous two-phase motor

    Publication Year: 1987, Page(s):57 - 60
    Cited by:  Papers (11)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (386 KB)

    In the paper, a static frequency convertor with inverter based on the amplitude modulation of the output voltage pulses for supplying asynchronous two-phase motor is presented. The operating principle of an inverter with a high fundamental content output voltage is described, and the higher harmonics spectrum of the output voltage is analysed. View full abstract»
