The utility model relates to a high voltage generator for video indicators used to transport anode high voltage to a CRT. The high voltage generator for video indicator is composed of an iron core, a main coil insulatively wound and covered on the iron core, a high-voltage coil insulatively wound and covered on the main coil, and a high voltage gold foil capacitor insulatively wound and covered on the high-voltage coil. The innermost layer of the high voltage gold foil capacitor is connected with the high voltage end of the high-voltage coil, and the outermost layer of the high voltage gold foil capacitor is connected with ground potential. The iron core can be designed to be an upper casing with center convex posts and a lower casing with center convex posts. The upper casing and the lower casing are assembled to form a closed magnetic circuit and an encapsulating outer shell. The high voltage generator for video indicators can effectively decrease the electro magnetic interference, reduce the volume of high voltage devices, simplify assembly program and reduce cost.
