Abstract
For the formation of an electric signal corresponding to the x-ray tube voltage, the high voltage transformer is provided with a low voltage winding. The low voltage at the terminals of the low voltage winding is conducted to the exterior of the tank. Here, a low voltage rectifier circuit is connected which corresponds in its circuit configuration to the high voltage rectifier circuit so that the electric signal supplied by the low voltage rectifier circuit accurately corresponds to the x-ray tube voltage and can be used for control purposes. The high voltage rectifier circuit and the low voltage rectifier circuit can operate as voltage multipliers.
Claims2
An x-ray diagnostic generator comprising an oil-filled tank, a high voltage transformer, a high voltage rectifier circuit, and an x-ray tube arranged in said oil-filled tank, the high voltage rectifier circuit being connected for supplying an x-ray tube high voltage to said x-ray tube, and a circuit arrangement for the formation of a signal corresponding to the x-ray tube high voltage, characterized in that the high voltage transformer (4a) is provided with a tap (6a) for supplying a low voltage which is conducted out from the tank (1a), and said circuit arrangement comprising a measuring rectifier circuit (8) outside said tank and connected for energization by the low voltage from said tap and having the same circuit configuration as the high voltage rectifier circuit (3) such that said measuring rectifier circuit supplies an electric signal corresponding to the x-ray tube high voltage.
