Abstract:
A pulsed high voltage power supply for use in a radiography system having a photonic radiation source with first and second high voltage electrodes, the pulsed high voltage power supply comprising:a first high voltage step up transformer having a first primary winding with first and second ends and a first secondary winding connected to the first electrode;a second high voltage step up transformer having a second primary winding with third and fourth ends and a second secondary winding connected to the first secondary winding and to the second electrode;a low voltage power source coupled to the first end of the first primary winding and to the third end of the second primary winding; anda switching circuit having a first switching signal output coupled to the second end of the first primary winding and a second switching signal output coupled to the fourth end of the second primary winding, wherein the first and second switching signal outputs provide a first and second series of pulses respectively and wherein each pulse from the first series of pulses causes the first high voltage step up transformer to provide a first high voltage pulse to one of the first and second electrodes and each pulse from the second series of pulses causes the second high voltage step up transformer to provide a second high voltage pulse to the other one of the first and second electrodes so that a series of substantially uniform high voltage pulses is generated across the first and second electrodes of the photonic radiation source.
