Abstract
Primary () and secondary () windings are subjected to a significant heat stress during operation of a high voltage transformer. The present invention describes a high voltage transformer which is believed to have good temperature properties. This transformer may have a planar primary winding and a Litz secondary winding. The planar primary winding may abut against a planar face of the core () therefore allowing for a good heat exchange between these two elements. The Litz secondary winding and the planar primary winding may be cooled by means of a cooling medium.
