ABSTRACT:
A power supply for producing excitation of an X-ray tube filament of an unusually lightweight and readily portable X-ray machine is achieved through the use of multiple voltage multiplying-rectifying stages powered by a transformer driven at 25 kHz. A four amp-four volt electrical current is applied across the X-ray tube filament by the use of a multi-stage filament transformer array driven at 33 kHz. The multi-stage filament transformer array is interconnected to the multiple voltage multiplying-rectifying stage so as to limit the voltage potential between stages. The use of 25 kHz and 33 kHz driving signals eliminates cross talk between signal producing circuits.
