Problems solved by technology
In this regard, the existing idea is to place multiple magnetic resonance coils continuously under the roadbed or on both sides of the road where the mobile body is traveling, and to transmit electric energy to the mobile body in a high-frequency manner through magnetic coupling, which requires a large number of high-quality magnetic resonance coils. Coils and high-frequency signal sources, the disadvantages are that the cost is extremely high, the installation and debugging are extremely difficult, and the robustness of energy-efficient coupling cannot be guaranteed

The invention discloses a mobile power receiving body and a traveling wave non-contact power supply system using the same. An OCS occupies a large amount of space when it transmits electricity to themovable body, and it is easy to cause various kinds of faults when it meets bad weather. The present invention moves a power receiver including n receiving traveling wave coupling segments. The receiving traveling wave coupling section includes two powered open waveguides. Both inputs of the two power-receiving open waveguides are floating. The traveling wave non-contact power supply system usingthe mobile power receiver comprises a power supply module and a power receiving module. The power supply module comprises an AC power supply and a transmitting traveling wave coupling section. The transmitting traveling wave coupling section includes a power supply open waveguide. The power receiving module includes a mobile power receiver and a power management component. The power management module includes n rectifying circuit groups. The n rectifying circuit groups correspond to the n receiving traveling wave coupling segments in the mobile power receiving body, respectively. The inventioncan ensure continuous and efficient electric energy coupling in the process of long-distance and high-speed movement of the mobile power receiving body.
Description
technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a mobile power receiver and a traveling wave non-contact power supply system using the power receiver. Background technique [0002] Wireless power transmission technology is a hot spot in the development of power electronics technology. This technology can be widely used in household appliances, industrial robots, medical equipment, aerospace, oilfield mines, underwater operations and many other fields, and has great potential for technological change. In 2007, MIT Marin The professor's team used the principle of magnetic resonance to light up a light bulb two meters away, making humans deeply aware of the potential of wireless energy transmission. [0003] In various power supply systems, it is relatively difficult to supply power to mobile terminals, especially high-power mobile bodies (such as high-speed rail trains, etc.). Generally speaki...
