    Power electronics is a technology which is interstitial to all three of the major disciplines of electrical engineering: electronics, power, and control. Yet its rapidly expanding significance has not been widely recognized, and the historical parochialism of specialists within the technology has stifled communication and cooperation in solving increasingly challenging problems. This paper calls f... View full abstract»

    Publication Year: 1974, Page(s):42 - 56
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5840 KB)

    Synchronous motors must be designed to have torque-speed characteristics which will match the load they are to accelerate. Motor designers have several parameters at their disposal for shaping the torque-speed curve of the motor, perhaps even more than the induction-motor designer. Maximum utilization of this available motor torque may, however, depend upon the effectiveness of the control apparat... View full abstract»

    In just eleven years, 1962-1973, adjustable-speed drives based on the SCR have progressed from zero to perhaps 80 percent of the market. Their real advantages are incontestable, high performance, efficiency, and reliability versus low cost, weight, size, and maintenance. But compatibility of the SCR drives with the ac line has become a live subject, to be covered in three parts in this paper. 1) A... View full abstract»

    In pulsewidth-modulated inverters used for variable-frequency applications, a number of harmonic control policies can be used. Most of these policies are complex to implement by hardware. The most simple and yet effective technique is synchronizing or the synchronized harmonic control policy. This paper uses double Fourier analysis techniques to obtain the output harmonics as a function of pulsewi... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1496 KB)

    A new method is described in which the dc motor may regenerate power effectively to ac supply. The principle is similar to that with a dc chopper for regeneration of the power from dc motor to dc supply. In this new method, however, thyristor switches synchronizing to the ac supply are used instead of a dc chopper. The principle and the power calculations as well as experimental results are presen...

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1274 KB)

    The pulsewidth-moduated (PWM) inverter has many inherent characteristics that make it a good choice for use in modern man-made fiber drives. Its wide operating speed range without tap changes and constant dc bus for ease of ``ride through'' are two primary examples. Although drives using PWM inverters are well suited to man-made fiber applications, the inverter design is compatible with general in... View full abstract»
