Description

technical field

[0001] The invention relates to the technical field of radio transmission, in particular to a design method for a relay coil of a three-coil structure medium-distance wireless power transmission system Background technique

[0002] In recent years, with the continuous heating up of research on wireless power transfer technology and the continuous expansion of related application fields, more and more scientists have given sufficient affirmation to this technology. In contrast, the traditional cable transmission system presents more and more disadvantages. In special fields such as deep sea, coal mine, and chemical industry, a series of safety and constructive problems such as sparks, transmission line laying and maintenance difficulties have made these The industry urgently needs the favor of wireless power transfer technology. Since Tesla pioneered the field of wireless power transmission, many scholars at home and abroad have devoted themselves to it, but ...

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] Such as figure 1 Shown is a relay coil design method for a medium-distance wireless power transmission system with a three-coil structure, including the following steps:

[0031] Step 1), setting the transmission distance of the wireless power transmission system, the planned middle distance range is 1.0m≤d≤3m, and the middle distance is the transmission distance between the transmitting coil and the receiving coil. 1 to 3 meters is the general transmission distance range of the medium-distance wireless power transmission system, and it can also be appropriately expanded, generally limited to within 5 meters, otherwise the three-coil structure will not necessarily meet the constraints in the improvement of transmission efficiency and power. ① and ②;

[0032] The transmitting coil, the relay coil, and the receiving coil are all space spiral coils with the same ...
