Abstract
Abstract A high voltage generator comprises a transformer unit for boosting an inputted AC voltage and a rectifier unit for rectifying the AC voltage boosted by the transformer unit, the transformer unit and the rectifier unit being assembled as high voltage components, wherein the high voltage components are molded by a solid insulation material with the high voltage components being separated from each other by a predetermined distance to thereby form the high voltage components to a single block member. An electric conductive layer is formed on an outside surface of the block member. The high voltage generator is utilized for an X-ray generator and a DC high voltage output generated from the rectifier unit serves as a power supply for generating X-rays. A filament heating transformer is further disposed as a high voltage component for supplying an AC power for heating filaments of the X-ray tube. A high voltage cables are connected to an output side of the rectifier unit and portions of ends of the high voltage cables on a rectifier unit side are directly embedded in the solid insulation material. The solid insulation material is an epoxy resin, a phenol resin, a silicone resin, a urea resin or the like.
