Abstract: Provided is an approach for active control of cross currents flowing among multiple paralleled converters. Control of cross currents is achieved by using at least one proportional-integral (PI) controller and at least one resonant controller to target several selected dominant harmonics with infinite gains to ensure elimination of targeted harmonic cross currents in steady state. The cross currents are decomposed by into (1) common mode and differential mode components or (2) current phase domain components and each component is suppressed to a value approximately near zero using the controller. Also provided is a device comprises instructions, that, when executed by a processor, cause the processor to perform operations, which regulate and suppress cross current within a power system.

Abstract: A power converter arrangement is described. The power converter includes a dc link and a power converter. The dc link is operably connected between a generator, or other power source, that provides an output voltage in use and a dc network. The power converter includes an inverter connected across the dc link in parallel with the generator, an isolation transformer having a primary tap changer and a secondary tap changer, and a rectifier. The rectifier has ac terminals connected to the secondary tap changer, a first dc terminal connected to the dc link, and a second dc terminal connected to the dc network. The dc terminal voltage of the rectifier is therefore summated with the output voltage of the generator to provide a converter output voltage.

Abstract: An axial flux machine comprising a rotor mounted about an axis of rotation and having two axial faces. A first stator ring is positioned on the rotor adjacent to a first axial face, to define an air gap, between the first stator ring and first axial face. The first stator ring is formed by stator ring segments, each having a radially inner and outer edge. A second stator ring is positioned on another side of the rotor, adjacent to the second axial face, to define an air gap between the second stator ring and second axial face. The second stator ring is, also, formed by stator ring segments, each having a radially inner and outer edge and corresponding to a first stator ring segment. The stator ring segments are deflectable in unison in response to axial deflection of the rotor, to maintain the air gaps, due to link elements.
