    The wide usage of the silicon-controlled rectifier in high-power applications is due, to a large degree, to the inherent overload capability of thyristors. Motor drive applications, for example, are characterized by complex load duty cycles and short-time overloads when accelerating the motor. Welding cycles, zero-crossfiring power control, and pulsewidth-modulated inverters are other examples whe... View full abstract»

    A most vital part of the electric system in large commercial and industrial buildings is the service entrance. Unfortunately it is located in a "no-man's land" between the electric power company's system and the low-voltage system. Much better understanding of the disadvantages and danger in providing a single 6000-18 000-ampere service entrance into a building is needed by electric power company ... View full abstract»

    An efficient method for achieving continuously variable speed control of slip ring induction motors with fan-type load is described in which the motor slip is controlled by a thyristor converter. By means of motor winding tap changes, the rating of the thyristor converter is reduced to a fraction, typically one third, of the motor. The reactive kVA associated with the converter is similarly reduce... View full abstract»

    As an electromechanical transducer, the squirrel-cage induction motor is simple and rugged. With variable-frequency inverters it is possible to operate an induction motor over a wide range of speeds, supplying a constant horsepower load. Performance is a function of sizing of motors and sizing of inverters. These relationships are explored on a fundamental basis. View full abstract»

    Renewed interest in electric automobiles has spawned a large number of publications describing various vehicle propulsion techniques. Most of the motor controller schemes have been described as solid state and lossless. In this context, the term lossless is appropriate since it differentiates the switching type of motor controller from the dissipative variety. The latter controllers employ a matri...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2240 KB)

    Measurements of electric arc parameters are normally made with canventional electromechanical instruments with the tacit assumption that the measurements are mean values. This may be a close approximation in the case of dc arcs supplied from a battery or from a rectified and smoothed dc source. It is, however, not true for dc arcs in plasma torches, arcs supplied with unsmoothed dc, ac arcs used f... View full abstract»

    Vapor phase cooling of semiconductor circuit components using a sealed heat exchanger with natural convection to air can be an effective static method of heat removal. The salient characteristic of heat transport through the flow of vapor can be combined with the capability of "spreading" waste heat energy uniformly within a compact condenser of large surface area. An additional capability, exists... View full abstract»

    In the operation of ship-to-shore or ship-to-dock oil handling facilities, the spillage of petroleum products can and frequently will occur as a normal part of the operation. The vapours of the spilled product, under certain conditions, can form a hazardous atmosphere which, when ignited, will lead to explosions and fires. One of the potential sources of ignition has long been recognized as arcs r... View full abstract»

    The stability criteria for controlled electroheat processes, i.e., plastic extruders, arc furnaces, induction furnaces, plasma torches, fluidized beds, etc., is studied. A previous geometric approach was unilateral, in that stability criteria could be evaluated if the electroheat gain and the controller sensitivity were known, but the reverse procedure was not possible. Subsequent experience has s... View full abstract»

    In electroheat processes such as induction furnaces, arc furnaces, radiant furnaces, plasma torches, fluidized beds, etc., that are usually discontinuously controlled (because of the large power ratings involved) a great deal of confusion has existed as to the effect of derivative signals in the primary feedback loop. This has resulted in empirical design rules for the derivative feedback in contr... View full abstract»
