1. A drive unit comprisingan input terminal;

  • a capacitively loaded output terminal;

    a charging transistor connected between said supply terminal and said output terminal, said output terminal being connected through a rectifying member to said input terminal;

    a discharge circuit connected between said rectifying member and said input terminal, comprising a transistor having one electrode connected to said rectifying member, and another electrode connected to ground;

    said input terminal being connected to the base of said transistor in said discharge circuit by means of a differentiating network comprising a resistor and a capacitor connected in parallel between said input terminal and said base of said transistor in said discharge circuit;

    said output terminal being connected, through a capacitive member, to a center tapping of a voltage distribution circuit connected between said supply terminal and a control electrode of said charging transistor so that when said charging transistor is conductive, an additional control voltage is applied to said control electrode.
