Abstract
In a high voltage DC generator, the primary winding of a flyback transformer is responsive to an input pulse for inducing a high-voltage potential in the secondary winding. A first pair of first and second diodes are connected in series from one of the secondary windings to a first output terminal. A second pair of first and second diodes are connected in series from the other terminal of the secondary winding to a second output terminal. Two capacitors are cross-coupled between the terminals of the secondary winding and the junctions of the diodes of each pair. The first diodes of each pair are turned on in response to the input pulse and the second diodes of each pair are turned on in response to the cessation of the pulse. A ringing reduction circuit comprises a resistive element, a capacitive element and a diode element, the diode and capacitive elements being arranged such that when the first or second diodes of both pairs are conductive the diode element turns on the charge the capacitive element, the resistive element being in circuit with the capacitive element to pass a current in response to the cessation of the pulse to dissipate ringing energy during the trace period.
