CONTACTLESS POWER CHAIN

摘要

An imaging system (100) includes a stationary gantry (102) and a rotating gantry (104). The rotating gantry (104) includes a first component (110, 114, 116) supplied with first power and a second component supplied with second power, wherein the first and second power are different. A contactless power chain (118) includes a first transformer (202, 204, 306) for transferring the first power from the stationary gantry (102) to the rotating gantry (104) and a second transformer (202, 204, 306) for transferring the second power from the stationary gantry (102) to the rotating gantry (104). The first and second transformers (202, 204, 306) are shifted relative to each other along the longitudinal axis (108) by a pre-determined finite non-zero distance (240). In another embodiment, an imaging system (100) includes a stationary gantry (102) and a rotating gantry (104) that rotates about a longitudinal axis (108). A contactless power chain (118) transfers power from the stationary gantry (102) to the rotating gantry (104), wherein windings (214, 218, 230, 234) of the contactless power chain (118) are carried by a non-resin based carrier (700).
