ABSTRACT:
The present invention relates to a medical X-ray radiation power supply apparatus wherein a DC-operated switching circuit is connected at the primary side of a high voltage transformer, and a comparator circuit compares the voltage predetermined by a tube voltage setting circuit with an actual tube voltage detected by a tube voltage detector circuit, then the gain of a comparison voltage is raised so that the actual tube voltage can quickly reach the predetermined tube voltage value, thereby tube voltage errors, which are caused by short photographing time in a medical or breast X-ray photographing apparatus, are eliminated.
