    摘要： A multichannel, contactless power transfer system includes a primary power inverter disposed on a stationary side of the system, and an auxiliary power inverter disposed on the stationary side of the system. A rotary transformer has a primary side thereof disposed on the stationary side of the system and a secondary side disposed on a rotating side of the system. The rotary transformer is configured to couple primary power from an output of the primary power inverter to a primary power voltage output on the rotating side of the system, and is further configured to couple auxiliary power from an output of the auxiliary power inverter to at least one auxiliary voltage output on the rotating side of the system.

    摘要： In accordance with one embodiment, a contactless power transfer system is provided that comprises a stationary member including a power input configured to receive power at first voltage from a power supply. The system further includes a rotating member rotatably coupled to the stationary member and a rotary transformer. The rotary transformer has primary and secondary sides, with the primary side being disposed on the stationary member. The primary side has a primary winding that receives power at the first voltage from the power input. The secondary side is disposed on the rotating member and produces power at a second voltage. The secondary side has a rotating core and separate secondary sub-windings, each of which has forward and return paths that are circumferentially disposed about the rotating core. The forward and return paths of each of the sub-windings rotate proximate to, and are disposed a substantially equal distance from, the primary winding disposed on the stationary member.
