Abstract

See full text

A power delivery system includes a rotary transformer having a primary winding and a secondary winding and configured to transfer power between stationary coupling elements on a stationary side and rotational coupling elements on a rotational side. The rotational coupling elements share a central axis with the stationary coupling elements, and are adapted to rotate with respect to the stationary coupling elements. The power delivery system includes an isolation transformer that drives the primary winding of the rotary transformer, and a plurality of power inverter stages whose outputs are adapted to be summed and coupled to the rotary transformer. A plurality of output power converters receive transmitted power from the rotary transformer. A plurality of control elements, disposed on the rotating side, are configured to close a feedback loop on desired and actual performance of the output power converters, and to control the power inverter stages.
