Description
Technical Field
[0001] The invention belongs to the field of wireless power transmission technology, specifically relating to a wide-distance adaptive wireless power and information synchronous transmission device and its parameter design method. Background Technology
[0002] Wireless power transfer technology eliminates the constraints of cables, offering high efficiency and convenience. However, due to the lack of physical connection between the transmitting and receiving sides of a magnetic coupling mechanism, coil misalignment is a common characteristic of wireless power transfer systems. In numerous applications of wireless power transfer technology, not only is power transmission required, but the system also needs real-time communication capabilities to achieve functions such as output voltage feedback control, load detection, status monitoring, and multi-controller synchronization. Similar to power transmission, good anti-misalignment capability for information transmission is often desirable to facilitate the design of subsequent processing circuits. Besides radial misalignment, the vertical distance between the transmitting and receiving sides often changes in practical applications. To maintain stable power and information output, the system needs a wide range of distance adaptability. Compared to the power of power transmission, information is a weak signal with lower power, often resulting in crosstalk between energy and information during transmission. This is one of the problems restricting the development of wireless power-to-information synchronization technology, especially when the power transmission is high, as more crosstalk is induced and coupled into the signal coupling transformer. Therefore, there is an urgent need for a wide-distance adaptive wireless power and information synchronization transmission device and parameter design method to achieve stable output of energy and information when offset and transmission distance change.
