Pulsed high voltage radiography system power supply having a one-to-one correspondence between low voltage input pulses and high voltage output pulses.

摘要

A pulsed high voltage power supply for use in a radiography system includes a high voltage step up transformer having a primary winding with first and second ends and a secondary winding connected to a radiation source. The power supply further includes a low voltage power source coupled to the first end of the primary winding and a switching circuit coupled to the second end of the primary winding. The switching circuit generates a switching signal having a series of pulses such that each pulse from the series of pulses causes the high voltage step up transformer to generate a high voltage pulse across the first and second electrodes to form a series of substantially uniform high slew rate high voltage pulses across the first and second electrodes of the radiation source.
