12 Claims.
My invention relates to translating apparatus and has particular relation to apparatus of the type wherein electric discharge devices are utilized to control the power supplied to a load.
It is an object of my invention to provide apparatus for supplying power from a source to a load through a plurality of electric discharge devices wherein the magnitude of the power supplied shall be controlled by controlling only one of the electric discharge devices.
Another object of my invention is to provide apparatus for controlling the supply of power from a source to a load by utilizing a plurality of electric discharge devices only one of which is controlled wherein the controlled electric discharge device shall regulate the operation of the other electric discharge devices.
A further object of my invention is to provide apparatus for supplying power to a load by utilizing a plurality of electric discharge devices for controlling the supply of power wherein the power shall be supplied through a predetermined number of the electric discharge devices depending on the magnitude of the power required. While applicable to high vacuum discharge devices my invention is particularly valuable when applied to gaseous discharge devices.
According to my invention, I provide a system in which power is supplied to a load from a source through a plurality of electric discharge devices which preferably are ignition tubes. One of the devices is controlled in the usual manner and starting circuit of a second device is inductively coupled to the output circuit of the first device. The starting circuit of a third electric discharge device is inductively coupled to the output circuit of the last named device and any number of additional electric discharge devices may be included in the system in a similar manner.
When the first electric discharge device is energized, current is transmitted through its output circuit and the second electric discharge device is energized. The third electric discharge device is energized by the initiation of the discharge in the second device and subsequent devices are energized in a similar manner. When the load is non-inductive the interval of time which elapses between the excitation of the first electric discharge device and the last electric discharge device is of the order of only a few micro-seconds.
The novel features that I consider characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawing, in which the single figure is a diagrammatic view showing the circuit of a system constructed and operated in accordance with my invention.
The apparatus shown in the drawing comprises a plurality of electric discharge devices I, L
3 and 5. Each electric discharge device comprises an anode l and a cathode 5, preferably of mercury, in which a starting electrode ii, preferably of carborundum or other material having a resistance high in comparison with the resistance of mercury is inserted. When a current of predetermined magnitude is transmitted between the starting electrode H and the cathode 9 of any one of the devices i, 3 or 5, a discharge is initiated between the anode l and the cathode Si providing the potential impressed between the latter electrodes is of sufficient magnitude.
The primaries l3, I5 and il of transformers l9, 2! and 23 and additional impedances 25, 2'3 and 29 of any suitable type are connected in series with the principal electrodes 7 and 9 of each of the electric discharge devices i, 3 and 5 respectively and the series networks consisting of the principal electrodes "l and 9, the primaries l3, l5 and ll of the transformers i9, 25 and 23 and the impedances 25, 2'! and 29 are connected in parallel with each other. The secondary 3i of a transformer 33 whereby power is to be supplied to the system is connected between the terminals of the network through the load 35 to be sup-- plied. The usual control system Si is provided for the purpose of supplying starting current to energize one of the electric discharge devices I.
When current is supplied between the starting electrode II and the cathode 9 of the last named electric discharge device I a discharge is initiated between the anode l and the cathode 9, and current is transmitted through the load 35. My invention is particularly applicable to the supply of power to a load which is substantially of the non-inductive type. When a load of this type is supplied and the discharge in the electric discharge device is initiated, the current transmitted through the non-inductive load rises to its maximum value comparatively rapidly and a comparatively high electromotive force is induced in the secondary 39 of the transformer it, the primary it of which is connected in series with the principal electrodes 1 and 9 of the energized electric discharge device I.
IJO
all)
The secondary 39 of the transformer I9 is con nected in series with the starting electrode H and the cathode 9 of a second electric discharge device 3 and by the initiation of the discharge in the first device I an impulse of current of considerable magnitude is transmitted through the network including the secondary Ml, the starting electrode ll of the second device and the corresponding cathode 9. If the load 35 is or such character that the current transmitted through the electric discharge device I and the series connected impedance 25 is of sufficiently large magnituc the drop in potential across the second electric discharge device 3 may be of suificient magnitude to energize the latter device. The last mentioned device will therefore be energiaed by the cooperation of the impulse iii-- duced in the secondary d9 of the transformer l9 associated with its starting electrode it and the potential impressed between its principal elec trodes l and !3.
Similarly, a third electric discharge device 5 may be associated with the second device 3 in the same manner as the second device 3 is associated with the first device I. It is seen that ii the current required by the load 35: is comparatively small only one electric discharge de vice I will be energized. As the current increases the number of electric discharge devices which are energized increases and thus the active electric discharge devices I, 3 and 5 varies in accordance with the current supplied. It is to be noted that the load current for which each successive device in its turn becomes energized may be regulated by varying the magnitude of the impedanccs $25, 21 and 29. 11' additional elec tric discharge devices are not to be added beyond the device 3, the impedance 29 may of course, be omitted.
My invention has been herein shown and described as applied to electric discharge devices of the mercury pool type incorporating current responsive starting electrodes. 't is apparent that my invention is also applicable to electric discharge devices of the type wherein a dis charge is initiated when the potential impressed between a control electrode and one or the other of the principal electrodes is varied. 01" the devices of the latter type, I have found that gasfilled electric discharge devices of the hot cathode type, such as grid glow tubes and mercury-pool grid-controlled electric discharge devices may with advantage be utilized.
When grid-controlled devices are utilized, the initiating control potential is supplied between the control electrode and a principal electrode of one device, the principal circuit of this device is inductively coupled between the control electrode and the principal electrode of another device, the latter device being coupled to a third device in the same manner and additional devices being added in the same manner.
Although I have shown and described a certain specific embodiment of my invention, I am fully aware that many modifications thereof are possible. My invention therefore is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claims.
