Abstract: A power converter with a modular, compact architecture with a reduced component count is disclosed. The power converter includes parallel power conversion sections and utilizes one or more mutual coupling input inductors with multiple windings. The windings are connected in pairs in a differential mode between a power source and the parallel power conversion sections. Each power conversion section receives the same input voltage and generates the same output voltage. As a result of the winding connections and the same input and output voltages, the input of the power converter exhibits current balancing and sharing between each branch of the parallel configuration, allowing a single current sensor to provide a measurement of the current and a single controller to control operation of each of the power conversion sections.

Abstract: A system for compensating for a back emission current in an X-ray generator is provided. The system includes a transformer, a common, and a voltage source. The transformer is operative to provide power to an electron emitter of the X-ray generator. The common is electrically coupled to an anode of the X-ray generator.

Abstract: In an X-ray generator an X-ray tube includes an anode and a cathode and is energized with at least a first high voltage potential. A dynamic damper with a frequency dependent impedance is interposed between the X-ray tube and a source of the high voltage potential.
