Title Magnetic resonance coupling wireless energy transmission system optimization design
Abstract
Wireless energy transmission technology refers to that the electrical equipment gets energy from the power by non-contact way, and due to no physical connection, it has high security and ease of use. Wireless power transmission system based on magnetic coupling resonance technology has farther transmission distance, higher efficiency, and no radiation, and it will have broad application prospects, so it is very important to study the technology.
This article is based on the four coil coupling resonance model, with the method of impedance mapping, four coil model is equivalent to a single coil model, and establishes the mathematical model; by calculating and analysis the influence of various circuit parameters on transmission characteristics of the system, proposes the optimization method together with optimization value; the simulation is carried out by using the simulation software. The results show that the components of the circuit parameters have great influence on the transmission characteristics, the proposed system optimization method is correct and feasible, and the optimal value can improve the transmission characteristics of the system.
