Abstract

The invention specifies a diode-split high-voltage transformer having a core, a primary winding and a high-voltage winding, which is arranged in chambers of a coil former, in which the chambers with the high-voltage winding lie below the primary winding, a conductive coating is arranged on the surface of the inner cavity of the coil former, and by virtue of a corresponding arrangement and wiring of the chambers, oscillations arising during operation in the high-voltage transformer induce capacitive currents on the conductive coating, the sum of which capacitive currents results approximately to zero. This can be achieved, for example in that by virtue of a symmetrical arrangement and wiring of the chambers with regard to the diodes, the oscillations induce capacitive currents on the conductive coating which occur in pairs with the same amplitude but in antiphase and thereby cancel one another out. In particular by virtue of an identical bottom thickness and approximately identical numbers of turns for all the chambers, the capacitive currents occur with a quantized amplitude, with the result that the values thereof can be defined in a simple manner since the stray capacitances are identical for all the chambers. This arrangement enables the earth connection to be omitted yet the screening effect of the conductive coating to be preserved.
