Abstract
A power transfer and monitoring device for an X-ray tube may include: an X-ray filament; a transformer including a primary coil and a secondary coil, wherein the secondary coil of the transformer includes a first leg, a second leg, and a middle leg; a current supply configured to supply a sinusoidal current to the primary coil of the transformer; and a calculation unit configured to measure a primary current of the transformer, configured to determine a synthesized transformer magnetizing current, and configured to subtract the synthesized transformer magnetizing current from the primary current of the transformer to determine a value of filament current through the X-ray filament. The first and second legs of the secondary coil of the transformer alternately supply current to a first end of the X-ray filament. The middle leg of the secondary coil of the transformer supplies current to a second end of the X-ray filament.
