Document Type and Number:
Japanese Patent JP2608050
Kind Code:
B2
Abstract:
A video apparatus includes a cathode ray tube (10) and a high voltage transformer (11). The high voltage transformer (11) incorporates a high voltage winding (24) having a tap (27) which provides a focus voltage for the electron gun assembly (12) of the cathode ray tube. The transformer (11) also includes a supply winding (31) which provides power to the electron gun assembly drive circuit (13). The supply winding (31) is wound so as to be closely coupled to the portion of the high voltage winding not associated with the generation of focus voltage, so that increasing beam current produces nonuniform loading of the high voltage winding (24).
