Cross-type segment power supply

PURPOSE: A cross-type segment power supply apparatus for being on and off controlled is provided to selectively a plurality of power feed modules by controlling a switch which controls the direction of a current which flows in the power feed module. CONSTITUTION: A power feed core(230) includes a magnetic pole which is serially arranged along the progressive direction of a moving body. A power feed module(210) is arranged to be serially in a row along the progressive direction of the moving body in the power feed core. Feeding lines(211,212,221,222) are arranged to have different polarities along the progressive direction of the moving body. A switch part controls connection between the feeding lines. The switch part includes a switch which on-off controls the feeding state of the power feed module.
