Patent ID: 8581437

Claim:
A power delivery system, comprising: a. a rotary transformer having a primary winding and a secondary winding, the rotary transformer operative to transfer power between one or more stationary coupling elements disposed on a stationary side of the rotary transformer and one or more rotational coupling elements disposed on a rotating side of the rotary transformer, the rotational coupling elements sharing a central axis with the stationary coupling elements and being operative to rotate with respect to the stationary coupling elements; b. an isolation transformer operative to drive the primary winding of the rotary transformer; c. one or more power inverter stages operative to provide input power to the primary winding of the rotary transformer, the power inverter stages having outputs that are operative to be summed and coupled to the isolation transformer; d. one or more output power converters operative to receive transmitted power from the rotary transformer and to convert the received power to a desired range for the rotational coupling elements; and e. one or more control elements disposed on the rotating side of the rotary transformer, the control elements operative to close a feedback loop on desired and actual performance of the output power converters, and further operative to provide to the stationary side of the rotary transformer one or more timing signals to control the power inverter stages; and f. an electrostatic discharger operative to substantially prevent static charge from accumulating on one or more of the rotational coupling elements; wherein the electrostatic charge comprises at least one of: a galvanic connection between the stationary side and the rotational side; and an ionic connection between the stationary side and the rotational side.
