Abstract:
A diode-split high-voltage transformer comprisinga core, a primary winding, a high-voltage winding, a coil former with an inner cavity, in which said core is located, with chambers, in which said high voltage winding is arranged, and with a conductive coating being arranged on the surface of said cavity, said coil former with said high-voltage winding lying between said primary winding and said core, said high-voltage winding being subdivided by a first and a second diode into a first, a second and a third partial winding, two partial windings in each case being connected to one another by one diode, said first and said third partial winding having an identical number of chambers and said second partial winding between said first and third partial windings having an even number of chambers and a focus connection for a focus electrode of a picture tube, the start of said first partial winding being coupled to ground and the end of said first partial winding, in the winding direction, being connected to the end of said second partial winding via said first diode, and the start of said middle partial winding being connected via said second diode to the start of said third partial winding, and the end of said third partial winding being coupled to a high voltage terminal.
