Abstract
Disclosed is a power supply apparatus for a linear motor transportation system having a number of discrete linear motor units serially arranged along a track to generate a moving magnetic field for driving vehicle. The apparatus comprises the linear motor units divided into a plurality of power supply systems each subdivided into a plurality of groups such that each of the power supply systems includes a series of ones of the linear motor units, the series of the linear motor units in each of the power supply systems being successively allotted to different ones of the groups; feeders provided respectively correspondingly to the groups in each of the power supply systems; feeder section switches for connecting respective one ends of the linear motor units in each of the group with corresponding ones of the feeders; a plurality of power supply devices provided respectively correspondingly to the groups in each of the power supply systems; and output side switches provided for connecting the respective outputs of the power supply device with corresponding ones of the feeders. The respective other ends of the linear motor units are connected with return path feeders and in each of the…
