    Analog dc tachogenerators are widely used as velocity transducers in industrial control systems. Despite the widespread use of miniature dc generators for this purpose, there are practical alternatives that should be considered for the analog measurement of velocity. The design and performance characteristics of homopolar and derived tachogenerators are discussed. These transducers are unique in t... View full abstract»

    In certain types of adjustable frequency induction motor drives, optimal control of the motor can be best implemented by using information on the motor slip frequency. Unfortunately, this generally requires the use of an electromechanical speed transducer coupled to the shaft. The presence of this transducer spoils the general characteristics of ruggedness and mechanical simplicity typical of an a... View full abstract»

    Current regulation plays an important part in the protection of solid-state drives operating from stiff voltage sources. Certain types of pulsewidth modulated (PWM) inverters, however, are not directly suited for peak or average output current regulation with induction motor loading. It is established in the paper that the typical output voltage response times of defined voltage waveform PWM inver... View full abstract»

    An optimization method, which will be of use in selecting the modulation technique and Carrier frequency for a PWM inverter system, is presented. The difficult decision, concerning the tradeoff between efficiency and unfiltered harmonic content, can be made with the help of this method. A relation between second-order filter rating and unfiltered harmonic attentuation, for optimum component values... View full abstract»

  • A Step-Up Phenomenon of the Thyristor Control Circuit with Series RLC Elements

    Publication Year: 1975, Page(s):531 - 539
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2723 KB)

    A circuit controlled by thyristors and having series RLC elements gives rise to a step-up phenomenon. The term step-up is defined with respect to the capacitance voltage on steady state operation, i.e., the ratio of the maximum peak value when controlled by thyristers to the peak amplitude when thyristors are short-circuited exceeds unity. The domain of possible step-up voltage is determined by th... View full abstract»

    The composition and use of an improved current rating system for high-current high-frequency thyristors is described. Commonly accepted methods for rating thyristors at low-frequency wide-pulsewidth conditions were not adequate for this task. To fill this void, a new system was developed that incorporates a combination of simultaneously measured high-frequency parameter data with a computer progra... View full abstract»

    Common motor circuit protection has consisted of thermal overload to sense motor overcurrent and a short circuit protective device which acts after a catastrophic condition has occurred. While this combination has provided adequate protection for the most common motor and motor circuit problems, it has not provided good protection against many of the problem conditions that can occur in the motor ...
