| With the rapid development of science and technology,the traditional wired charging system is unable to meet the requirements of convenience and safety.It is easy to break the cable charging,causing the electric spark,which has a great safety hazard in the special environment such as mine,and it is difficult to maintain,and the installation is complicated.Wireless power transfer technology is free from the dependence of traditional cable transmission on metal wires,and is more flexible and convenient for non-contact transfer of energy.In recent years,especially in the use of magnetic resonance,the multi-load radio can transmit more and more,becoming the current research hot spot.This paper briefly introduces the development history of radio and current research status.To transmit a solution for all kinds of radio transmission principle and their respective advantages and disadvantages are analyzed,identified this topic research scheme selection of magnetic coupling resonant radio transmission.Secondly,the system of single load is modeled and analyzed in the mode of circuit model and coupling mode,and the mixed analysis method is put forward.The multi-load circuit research is carried out,and the optimum transmission distance and the optimum matching impedance formula are analyzed.In this paper,the optimization of reactance compensation is proposed for cross-coupling,and the two optimization measures are made.Energy transmission system is the final design,change the load coil position,through the experiment on the opposite side coaxial,ipsilateral coaxial,with Angle,and so on and so forth for the transmission distance and Angle of deflection test,and comparing with the optimized system,the results optimization measures to better improve the performance of the system.This article is based on liaoning province key laboratory project project(LJZS003),has a certain research value. |
