Abstract

1,103,825. Capacitor supply systems for discharge lamps. ELECTRIC & MUSICAL INDUSTRIES Ltd. 13 May, 1965 [13 May, 1964], No. 19867/66. Heading H2H. [Also in Division H3] In a pulse generator of the type in which a capacitor or pulse forming network 13 is charged from the rectified output of a transformer coupled relaxation oscillator and subsequently discharged via a switching device (such as 14), the switching device is triggered by a signal induced in a winding of said transformer during the intervals in which the capacitor is not being charged. As described transistor 6 is regeneratively coupled by windings 4, 7 of a transformer so as to form a freerunning of triggered blocking oscillator, the duration of pulses from which is determined by the time taken for the current in winding 4 to reach a value such that transistor 6 is no longer saturated. Each high voltage pulse from the secondary winding 10 resonantly charges an artificial line 13 via a diode 11 which is subsequently discharged via a thyristor 14 and a pulse transformer 15 feeding a magnetron load 2. Thyristor 14 may be triggered by the next pulse from an auxiliary winding 17 after amplification, delay or differentiation at 18. The thyristor 14 may be replaced by a triggered or non-triggered spark gap or a thyratron. H2H: Electricity supply to flash tubes.-The invention may alternatively be applied to a Xenon flash tube which may be connected in place of thyristor 14.
