  • Frequency Spectrum Generated by Thyristor Control J
    Electrocomponent Science and Technology (C) Gordon and Breach Science Publishers Ltd. 1974, Vol. 1, pp. 43-49 Printed in Great Britain FREQUENCY SPECTRUM GENERATED BY THYRISTOR CONTROL J. K. HALL and N. C. JONES Loughborough University of Technology, Loughborough, Leics. U.K. (Received October 30, 1973; in final form December 19, 1973) This paper describes the measured harmonics in the load currents of thyristor circuits and shows that with firing angle control the harmonic amplitudes decrease sharply with increasing harmonic frequency, but that they extend to very high harmonic orders of around 6000. The amplitudes of the harmonics are a maximum for a firing delay angle of around 90 Integral cycle control produces only low order harmonics and sub-harmonics. It is also shown that with firing angle control apparently random inter-harmonic noise is present and that the harmonics fall below this noise level at frequencies of approximately 250 KHz for a switched 50 Hz waveform and for the resistive load used. The noise amplitude decreases with increasing frequency and is a maximum with 90 firing delay. INTRODUCTION inductance. 6,7 Literature on the subject tends to assume that noise is due to the high frequency Thyristors are now widely used for control of power harmonics generated by thyristor switch-on and the in both d.c. and a.c. circuits. The advantages of design of suppression components is based on this. relatively small size, low losses and fast switching This investigation has been performed in order to speeds have contributed to the vast growth in establish the validity of this assumption, since it is application since their introduction, when they were believed that there may be a number of perhaps basically a solid-state replacement for mercury-arc separate sources of noise in thyristor circuits.

Presper Eckert Jr. 1 When we speak of graphics, we think of images. Be it the windowed interface of a personal computer, the tactile swipe of icons across a mobile device, or the surreal effects of computer-enhanced film and video games—all are graphics. Understandably, then, computer graphics are most often understood as the images displayed on a computer screen. This pairing of the image and the screen is so natural that we rarely theorize the screen as a medium itself, one with a heterogeneous history that develops in parallel with other visual and computa - tional forms. 2 What then, of the screen? To be sure, the computer screen follows in the tradition of the visual frame that delimits, contains, and produces the image. 3 It is also the skin of the interface that allows us to engage with, augment, and relate to technical things. 4 But the computer screen was also a cathode ray tube (CRT) phosphorescing in response to an electron beam, modified by a grid of randomly accessible memory that stores, maps, and transforms thousands of bits in real time. The screen is not simply an enduring technique or evocative metaphor; it is a hardware object whose transformations have shaped the ma - terial conditions of our visual culture.

H. Dodd) We are continuing our practice of having two installation days per week and have made very good progress in eliminating weak points in the circuits and readying the computer for operation with the new terminal equipment. Plans are now being formulated for a change in the positions of some of the ES control circuits so that a spare ES digit column can be in­ stalled. Thus when the second bank of storage is in operation, there will be one parity digit and one spare digit available for each bank. An inten­ sive program of testing of the various digit columns in Electrostatic Storage has been going on for several weeks with the view of determining the reasons for positive switching and, in general, increasing the reliability of operation of Electrostatic Storage. The evaporative condenser in the present air-conditioning system has been moved to a new location to prepare for the installation and tie-in of the new air-conditioning system.

  • Active Discrete Components
    Christiansen_Sec_05.qxd 10/28/04 10:40 AM Page 5.28 Source: STANDARD HANDBOOK OF ELECTRONIC ENGINEERING CHAPTER 5.2 ACTIVE DISCRETE COMPONENTS George W. Taylor, Bernard Smith, I. Reingold, Munsey E. Crost, Gregory J. Malinowski, John F. Donlon, Edward B. Hakim POWER AND RECEIVING TUBES George W. Taylor, Bernard Smith Introduction Power and receiving tubes are active devices using either the flow of free electrons in a vacuum or electrons and ions combined in a gas medium. The vast majority of uses for low-power electron tubes are found in the area of high vacuum with controlled free electrons. The source of free electrons is a heated material that is a thermionic emitter (cathode). The control element regulating the flow of electrons is called a grid. The collector element for the electron flow is the anode, or plate. Power tubes, in contrast to receiving-type tubes, handle relatively large amounts of power, and for reasons of economy, a major emphasis is placed on efficiency. The traditional division between the two tube categories is at the 25-W plate-dissipation rating level. Receiving tubes traditionally provided essential active-device functions in electronic applications. Most receiving-type tubes produced at the present time are for replacement use in existing equipments. Electronic functions of new equipment designs are being handled by solid-state devices. Power tubes are widely used as high-power-level generators and converters in radio and television transmit- ters, radar, sonar, manufacturing-process operations, and medical and industrial x-ray equipment. Classification of Types Power and receiving-type tubes can be separated into groups according to their circuit function or by the num- ber of electrodes they contain.
