Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] figure 1 Shown is the basic composition of the first embodiment of the present invention: the mobile non-contact power supply system solution one using segmental power supply. Such as figure 1 Shown:

[0040] The rectification filter 1 rectifies the alternating current of the grid into high-voltage direct current, and supplies power for each resonant converter. The plurality of primary winding coils are divided into N partitions 13-0, 13-1, 13-2, . . . 13-N. The following takes 13-1 partition as an example to illustrate the structure of the mobile non-contact power supply system scheme 1 using segmental power supply, and the other partition structures are the same as 13-1 partition.

[0041] In the 13-1 partition of the primary winding coil, the input terminals of the rectification filter 1 are respectively connected to the alternati...

Abstract

The invention discloses a movable type non-contact power supply system in which subsection power supply is adopted. Two direct current buses arranged on the ground are connected to resonance current transformers respectively through direct current switches, primary power supply winding coils arranged on the ground are respectively divided into N partitions, N is a positive integer, each partition is divided into 2k subsections capable of supplying electricity independently, k is a positive integer and is the same as below, each partition is internally provided with one resonance current transformer to supply electricity, one resonance current transformer can supply electricity to k primary winding coils, and every two adjacent primary winding coils are supplied with electricity through different resonance current transformers respectively. When secondary winding coils pass through the gap between every two adjacent primary winding coil subsections, the two primary winding coils are independently supplied with electricity at the same time. The end of each primary winding coil is provided with a position detecting device, when the position detecting devices detect the secondary winding coils, the corresponding diverter switches are turned on to supply electricity to the primary winding coils connected with the switches, and the primary winding coil sections not covered by the secondary winding coils are not supplied with electricity.

Description

technical field [0001] The invention relates to a subsection power supply device of a contactless power supply system. Background technique [0002] Contactless power supply, also known as non-contact power transmission, refers to the transmission of power from one side (power supply side) to the other side (load side) based on the principle of electromagnetic induction without direct electrical contact. Mobile contactless power supply refers to a special contactless power supply method that can transmit electric energy even if there is relative movement between the two sides, that is, the power supply side and the load side. [0003] Compared with the traditional power supply, the advantages of the mobile contactless power supply system are: (1) There is no direct contact between the power supply system and the load, there is no exposed live conductor, and there is no risk of electric shock; (2) No friction, no contact sparks ; (3) No carbon dust caused by friction, easy m...
