ABSTRACT:
A high voltage, high power DC power supply includes a single turn primary winding driven through a resonating capacitor by an AC source having a frequency in excess of about 100 kHz. The primary winding includes a pair of concentric cylindrical metal walls having opposite ends electrically connected to each other. A volume between the walls includes plural secondary winding assemblies, having different axial positions along the walls. Each of the assemblies includes an annular magnetic core surrounding the interior wall, a winding on the core and a voltage doubler rectifier. DC voltages developed across each secondary winding assembly by the rectifier are added together to provide the high voltage, high power output. The power supply energizes an X-ray tube having a grounded anode and a cathode at a DC voltage of approximately -150 kV, with a power requirement of between 15 and 60 kW. The power supply and X-ray tube are mounted on a rotatable gantry including a slip ring assembly for coupling a relatively low voltage excitation source to the power supply.
