  • Patent number: 5629589
    Abstract: A diode-split high voltage transformer for a television receiver includes a coil form having a plurality of axially aligned cells. The cells are arranged in groups and are separated by fins. Partial windings are individually arranged in the cells. A plurality of diodes is arranged about the edge of each fin and and substantially normal to the of the form. The partial windings and the diodes are alternately connected in series. Each of the fins includs a ramp-shaped recess tangentially extending from the fin edge to the bottom of the cell adjacent to the fin to provide space allowing the winding wires to stay clear of the partial windings.
    Type: Grant

  • Patent number: 5576681
    Abstract: A high voltage transformer for a television receiver includes a primary winding and a secondary winding. The secondary winding is compartmentalized and is separated from the primary winding by a space. The secondary winding has a plurality of partial windings which are arranged in cells of a compartmentalized coil form and are connected to one another by diodes. The partial windings are positioned and dimensioned with respect to the primary winding to cause substantially equal pulse voltages of like polarity to exist at the neighboring portions of the primary winding and the partial windings in the vicinity of the space, to substantially eliminate pulse electric fields in the space.
