Abstract

1,110,123. Protective arrangements. J. STONE & CO. (DEPTFORD) Ltd. 19 April, 1966 [26 April, 1965], No. 17401/65. Heading H2K. An arrangement for protecting semi-conductor apparatus comprises a thyristor 3 connected across the supply to the apparatus and a Zener diode 4 or other device connected to the apparatus and responsive to overvoltage conditions to apply a control signal to the thyristor to render it conducting to short-circuit the apparatus. A fuse 7 is then blown, or an automatic circuit-breaker is operated, by the shortcircuit current to interrupt the supply to the apparatus. As shown, the Zener diode 4 is connected in series with a resistor 5 across the supply to the apparatus 1 and, in the event of overvoltage, conducts. The voltage across the resistor 5 is applied to the gate of the thyristor 3 through a variable resistor 6 to render the thyristor 3 conducting, a slight delay being provided by capacitors 9 to prevent undesired operation under transient conditions. Should the supply be alternating current, then diodes 10, 11 are connected as shown. Figs. 2 and 3 (not shown), illustrate the application of the arrangement to the field circuits of a D.C. generator and an alternator. By providing a further Zener diode 4 and resistor 5 the arrangement may be connected to provide overcurrent protection. Reference has been directed by the Comptroller to Specification 1,005,261.
