Abstract

The embodiment of the invention discloses a wireless power supply system for a vehicle and a transportation system. The wireless power supply system comprises a power supply module, a feed shielding circuit and a traction unshielded line. The power supply module provides a power supply to the traction unshielded line through the feed shielding circuit such that a powered device senses the power supply by using the electromagnetic induction principle to obtain electrical energy. The traction unshielded line includes at least two block segments, the block segments are isolated from each other, the length of each block segment is smaller than a resonant wavelength of power supply voltage and current, the power loss on the traction unshielded line is reduced, the power cost is reduced, and theefficiency of wireless power supply is improved.

Description

technical field [0001] The present application relates to the technical field of transportation, in particular to a wireless power supply system for vehicles and a transportation system. Background technique [0002] In the field of transportation, the existing wireless power supply technology uses battery induction. The basic principle is to generate resonance in the wire by increasing the frequency and voltage of the output power of the power supply side, and the power receiver senses the single conductor line. The magnetic induction effect obtains the electrical energy output to the powered equipment. However, the inventor found in the research that due to the large inductive resistance of the wire under high-frequency conditions, the power consumption on the wire is relatively large, which will cause the cost loss of power supply, and the cost of wireless power supply is high and the efficiency is low. Contents of the invention [0003] In order to solve the problems ...
