Abstract
A CT system includes an x-ray source, a high-voltage power supply (HVPS) coupled to the x-ray source, and a high-frequency power distribution unit (HFPDU) having an input bus that is coupleable to a three-phase source, and having an output bus. The HFPDU includes a three-phase rectifier coupled to the input bus and configured to output a DC current to an inverter, the inverter configured to convert the DC current to an AC current, and output the AC current to a primary winding of an isolation transformer, and the isolation transformer having a secondary output to an isolation transformer, that is coupled to a full bridge rectifier, to produce DC current to the output bus and to DC bus loads of the CT system.
