Abstract
A high voltage transformer (Tr) includes a primary winding (Lp), secondary windings (Ls1, Ls2, Ls3), and diodes (Di) coupled between successive secondary windings. The polarity of the diodes and the secondary windings is selected such that the flyback voltages across each of the secondary windings are summed via conductive diodes during at least a part of a flyback period (Tf) for generating a high voltage. A damp-circuit (1) comprises a rectifier element, a load (L), and a further winding (Ls4) of the high voltage transformer. These elements are arranged with respect to one of the secondary windings such that the further winding and the one of the secondary windings form a capacitance (Cd) across the load. The diode (D) is non-conductive during the flyback period. In this way, electrical oscillations of the high voltage transformer are damped.
