Title: Static switching systems
Inventor: DAVIS REX MOUNTFORD
IPC: H03K17/72
Filed: 1963-07-20
Abstract: 1,095,091. Switching circuits. BRUSH ELECTRIC ENGINEERING CO. Ltd. June 19, 1964 [July 20, 1963], No. 28812/63. Heading H3T. In a switching system in which each of a plurality of static switching devicss (e.g. thyratrons or thyristors) connect respective loads in parallel to a common D.C. supply, turn off of the devices is effected by means in the supply line to the loads and switches which reverses the supply voltage. In Fig. 1 three loads shown by way of illustration as resistor 14, inductor 15 and motor 16 may be connected to the supply rails 1, 2 by rendering conducting a corresponding thyristor 11, 12 and 13. Extinguishing of the thyristors is effected by rendering conducting a further thyristor 5. This causes a current in the main thyristors to be diverted and initiates a resonant discharge of capacitor 10 through inductor 9 and thyristor 5. At the end of a half cycle the resonant current reverses eventually rises to a value such as to switch off thyristor 5. A reverse voltage is now applied to line 6 by the capacitor and this extinguishes the main thyristors. The current in the inductor continues through diode 8. When the voltage of the supply line restores to its previous value only those of the main thyristors which have a forwardly biased gate voltage switch on again. The momentary interruption of the current through the loads not required to be switched off is either negligible or where the load is inductive may be continued during the interruption by the provision of rectifiers 17, 18. The switch-off thyristor 5 may receive a continuous train of gate pulses from a blocking oscillator (Fig. 3, not shown) so that when the gate voltage is removed from one of the main thyristors (Fig. 4, not shown) it will switch off at the next blocking oscillator pulse. Alternatively a monostable blocking oscillator may be used (Fig. 5) and this may be arranged so that when one of the switches 31b, 32b, 33b is opened to remove the gate voltage from the corresponding main thyristor a pulse is applied through a corresponding one of capacitors 31c, 32c, 33c to a blocking oscillator 21 to cause it to produce an output in winding 22c which renders conducting the switch-off thyristor 5. The switch-off network 3 may be replaced by a balanced network with chokes in each supply line (Fig. 2, not shown).
