A power supply system for a linear motor type transportation system includes a series of driving coils disposed along a railroad track for producing a moving magnetic field to drive a train, a plurality of feeding blocks disposed along the railroad track for supplying electric power to the series of driving coils, a plurality of power converters each connected to the corresponding feeding blocks to supply electric power to each corresponding feeding section composed of the feeding blocks, and a plurality of block switches connected between neighboring two feeding blocks of the feeding blocks. Each of main controllers for determining each feeding section includes a boundary candidate operation unit for calculating a feeding section boundary candidate of a power converter between the neighboring power converters on the basis of the position information of a train being present in the feeding section, a section boundary determining unit, and a feeding block switch control unit for controlling on-off states of the block switches so as to define the feeding section boundary between neighboring two feeding blocks. Each boundary determining unit selects one boundary from two boundary candidates supplied from the boundary candidate operation units of the main controller of the neighboring two power converters.
