Abstract: A power conversion system includes a hybrid power converter phase unit including three voltage inputs, a voltage output, a pair of outer switches between the voltage inputs and voltage output, and a pair of inner switches between the voltage inputs and the outer switches. The power conversion system includes a controller in electrical communication with the inner and outer switches. The controller is configured to selectively disable or enable the inner switches by switching the inner switches OFF or ON. A method includes selectively disabling or enabling inner switches in a hybrid power converter phase unit with a controller such that the hybrid power converter phase unit is a 3-level converter when the inner switches are ON and enabled in a 3-level mode and a 2-level converter when the inner switches are OFF and disabled in a 2-level mode.

Abstract: A system comprises a resonant coupling having a first coil and a second coil, wherein the first coil is mounted to a first body that is stationary relative to a second body that is configured to rotate relative to the first body, and wherein the second coil is mounted to the second body to rotate relative to the first coil. The first and second coils are configured so that alternating current in the first coil induces an alternating current in the second coil to transfer electrical power from the first coil to the second coil wirelessly. The first and second coils do not contact one another regardless of whether the first and second bodies rotate relative to one another.
