Segment using one kind of movable contactless power supply system

Segment using one kind of non-contact power supply system of the mobile, which is disposed on the ground to two DC bus by DC resonant converter switches respectively supply the primary winding coil arranged on the ground into N (N is a positive integer ) partitions, each partition into 2K (k is a positive integer, the same below) may be an independently powered pieces, each partition is provided with a resonant power converter, a resonant converter may be a primary winding coil to the power of k , adjacent two of the primary winding current coils are powered by different variants of resonance. When the secondary winding coil 2 through the primary winding of the coil segments adjacent to the gap, while the two primary winding coil independent power supply. A primary winding in the primary winding of each coil is attached to an end portion position detecting means, when the position detecting means detects a secondary winding of the coil, the corresponding switch is closed, supplying power to the primary winding coil connected thereto, a secondary winding of the coil is not covered coil segment is not energized.
