Definitions

  • WITNESSES INVENTOR Jury en 1/011 lssenaorf' v I BY W ATTORNEY Patented June 13, 1939 UNITED STATES TRANSLATING DEVICE Jiirgen von Issendorf, Berlin-Siemensstadt, Germany, assignor to Westinghouse Electric, &
  • This invention relates to a scheme for controlling arc rectifiers by means of alternating voltages applied to the control grids, or to the outer layers of the anode tubes; said alternating voltages being adjustable in such a manner that at any instant the grids or the outer layers can be brought either at a positive potential sufficient to ignite the corresponding anode, or at a negative potential sufiicient to make the corresponding anode inoperative.
  • the alternating voltages applied to the controlling members, in line with this invention are not sine-shaped, but are given such a curve shape that the transitions of the controlling members from one operating condition to the other, and more inparticular the transitions from the inoperative condition to the ignited condition, will take place almost instantaneously.
  • a curve and the connection diagram shown in Figs. 1 and 2 have reference to a known arrangement, and will be used for making comparisons.
  • connection diagram of Fig. 7 relates to Fig. 6..
  • Comparisons can be based on the sine-shaped voltage curves of Fig. 1, representing the voltage of a rectifier (or valve) anode, and the voltage of the corresponding grid, for the connection shown in Fig. 2.
  • the main transformer is designated by I4;
  • I5 are the anodes of the rectifier I6 which has grids I! connected through protecting resistors I8 to the transformer I9.
  • the cathode of rectifier I6 is designated by 20; resistor 2
  • FIG. 7 A connection diagram embodying Fig. 6 is given V in Fig. 7.
  • the control members I are connected through ohmic resistances 2, or through other current limiting devices, to a direct current source 3, and further through glow discharge tubes 4 to an'alternating current source 5.
  • This arrangement is such that when the ignition voltage of each individual glow discharge tube is being periodically exceeded, a periodical current impulse will flow through that particular tube, changing instantaneously the voltage applied tothe corresponding controlling member.
  • a fundamental voltage, negative in respect to the cathode is being applied to the grids.
  • the glow discharge lamps 4 is being applied the sine-shaped secondary voltage of the induction regulator 6.
  • the glow discharge lamps have quite specific ignition and extinction voltages. This means that as soon as the ignition voltage of a glow discharge lamp is exceeded, that particular lamp will let the current go through, and the corresponding anode grid is given at the very same instant a (more positive) voltage sufiicient to ignite the anode are.
  • I indicates the time curve of the anode (single-phase) voltage, and 8 the grid voltage.
  • Fig. 6, 9 indicates the secondary (phase) voltage of the induction regulator, III the value of the ignition voltage, II the time curve of the cathode potential, I2 the value of the extinction voltage of the glow discharge tubes.
  • Curve I3 represents the voltage of the controlling grid.
  • the normally sine-shaped alternating voltages available for application tothe controlling members can be distorted by means of transformers or reactors with saturated iron in such a manner that the time curve of the voltages will have a steep increase, over a certain interval, at least once during each cycle of the alternating voltage (Figs. 3 and 4).
  • the normally sine-shaped alternating voltages available for application to the. controlling electrodes can be modified, as shown by Fig. '7, by means of gas-filled discharge tubes or high-vacuum electronic tubes, so that the amplitudes of the voltages, particularly those of negative polarity, will be reduced by diverting or limiting the current flow, whereas the steep parts of the time curve of the voltage remain unchanged. The voltages.
  • controlling members can be supplied by a special rectifier of small capacity, which can also be equipped with controlling members, influenced by a control current of suitable curve shape.
  • This additional rectifier makes it possible to make the instant of ignition of high-vacuum electronic tubes independent of the current load.
