Abstract
The present invention relate to an X-ray photographing apparatus, and more particularly, to a high voltage driving circuit for X-ray tube, in which a first voltage multiplying rectifier unit and a second voltage multiplying rectifier unit are in series connected to each other based on a high voltage generation unit to stably convert a high voltage power generated from the high voltage generation unit into a drive power for an X-ray tube with high energy efficiency, and in which a plurality of isolation transformers or high voltage transformers is in series connected to each other in the high voltage generation unit to divide a voltage of the second voltage multiplying rectifier unit into a withstanding voltage of the isolation transformers or the high voltage transformers, thereby ensuring excellent insulation properties.
