Discharge module for high voltage x-ray tubes

摘要

Discharge module which is formed by three circuits, a control and measurement circuit for X-rays, a voltage division circuit between serial switches, which is independent from the previous one, and a third circuit of the charge short circuit, which in turn is formed by a successive or slave trip circuit of the switches and another main discharge circuit through the switches; due to the established configuration, a much improved radiation control is achieved as it is not affected by unforeseen agents, the short circuit current is not restricted to the port current of the switches, and residual voltage of the switches is reduced.

主权项

1. A discharge module for high voltage cables of X-ray tubes comprising three circuits:
a control and measurement circuit through which a current IRx circulates through two shunts, diodes, the high voltage supply source and the X-ray tube; a circuit which is a voltage division circuit among switches (7), through which leakage current ILK circulates; a circuit which is a short circuit of the charge formed by the X-ray tube and the high voltage capacities; and wherein the leakage current ILK circulates only through the voltage division circuits and not through the control and measurement circuit.
