  • Patent number: 4855889
    Abstract: High-tension generator circuit for a particle detector, having a transformer (8, 9) and a voltage step-up circuit (10). The primary 8 of the transformer is fed by means of a power transistor 7 whose drive transistor 6 is controlled by means of a resistance-capacitance circuit (4, 5). In each conduction period of the primary the secondary brings about a reversal of the polarity of the capacitance.
