The invention relates to a high-voltage transformer arrangement which
converts to the direct current voltage from a direct current voltage
source (2) into a direct current voltage output signal (V.sub.out), using
a current inverter (4) and a transformer (8) to an output rectifier (12),
which is connected downstream, and a filter (14). The transformer (8) has
a transformer core comprising several interruption points in the magnetic
path, at which insulator sections are located. The individual core
sections are controlled by potential. The separate transformer core
sections together with their corresponding windings form a primary system
and a secondary system, which is separated from said primary system both
spatially and in terms of potential, having a relatively high stray
inductance. Said stray inductance may be used in conjunction with other
components for the resonant mode of the high-voltage transformer during
the switching operations (quasi-resonant mode) and for adjusting an
approximately sinusoidal transformer current during the current inverter
clock cycle. At the same time, the spatial separation simplifies the
insulation of the transformer parts.
