Description

technical field [0001] The present invention relates to the technical field of space electric field coupling wireless power transmission, in particular to a fractional order serial electromagnetic field double coupling wireless power transmission system. Background technique [0002] According to the different mechanisms and methods of power transmission, wireless power transfer technology can be roughly divided into magnetic field coupled wireless power transfer technology, electric field coupled wireless power transfer technology and microwave wireless power transfer technology. Among them, although the transmission distance of the microwave type can reach a long distance, the efficiency is extremely low, the power is small, and the dissipation is serious, so it is rarely used at present. In practical applications, the magnetic field coupling type and the electric field coupling type have been studied more in recent years due to their higher transmission power and higher e...

Problems solved by technology

However, the traditional series electric-field coupled and magnetic-field coupled wireless power transfer systems are based on integer-order components, and the degree of freedom in system parameter design is small, and there are few adjustable factors for output power and transmission efficiency. Due to technical limitations, it is difficult to achieve higher power and longer distance wireless power transmission
