Abstract

An improvement introduced in x-ray apparatus for diagnosis with alternating current power supply, in which the x-ray tube is automatically charged with a power that varies with the chosen charging time, characterized by the fact that the switch the time is designed in such a way that in the range of the connection times of only a few periods of the alternating current supply the successive values of the connection time differ in at least one half period and that each of these values is associated with two or more positions of the time switch for different loads of the x-ray tube.
