Design Of ICPT System Based On Wide Coupling Coefficient Range

Induction coupled radio transmission technology(ICPT)is a research hotspot in the field of power electronics in recent years.Compared with the traditional mode of contact type electric energy transmission,ICPT technology has the advantages of convenient,safe,easy to maintain,strong environmental adaptability and so on,and has received great attention in all fields.The basic principle of ICPT technology is based on the principle of electromagnetic induction,which is realized through the coupling of the original side coils,so the coupling mechanism is a very important part of the ICPT system.For different application environment,the coupling mechanism of ICPT system has its corresponding design.The coupling mechanism of ICPT system which is applied to the UAV,implantable medical devices and other fields has great changes in the coupling distance,so this paper is aimed at how to maintain the electric energy under the condition that the coupling distance varies in a certain range.Efficient and stable transmission of research and design.In this paper,a LCC-S asymmetric compensation topology is proposed,whose primary side is compound resonance and the secondary side is the basic resonance.It has a larger resonant capacity than the single stage LC resonant converter;it has better robustness,and the voltage and current stress of the switch devices are smaller at the same power level.Particle swarm optimization is used to optimize the coupling mechanism parameters and improve the robustness of the system.The main contents of this paper are the following 5 points:1.introduces the research status of radio energy transfer technology.2.according to the analysis of the ICPT system under the condition of the mutual inductance coefficient,the core problem is obtained,and the basic module of the system is designed.3.through the establishment of a mathematical model,the relationship between the output power,efficiency and mutual inductance of the four basic topologies is obtained,and the characteristics of the four basic topologies are analyzed,and the asymmetric topology with the original side as complex resonance and the side side as simple resonance is further discussed.4.using particle swarm optimization algorithm to get the best parameters to enhance the robustness of the system.5.use electronic electronic devices to set up each module of the system and expand the UAV wireless charging experiment.First,the experimental data are analyzed separately,and then the theoretical results in this paper are compared,and the reliability,correctness and feasibility are judged objectively.
