Research On Wireless Power Transmission System With Induction Heating Function

Cars have become an indispensable means of transportation in people's lives,and more and more items are placed in the car,such as food,drinks,mobile phones,computers and so on.In this thesis,a set of wireless energy transmission system with induction heating function is designed,which can be applied to the automobile.The wireless energy transmission system and induction heating system can share a high-frequency power transmitter,the secondary edge circuit of the wireless power transmission system is composed of a resonant coupling mechanism and load,which is coupled with the original edge circuit to wirelessly charge the electronic products;The secondary edge circuit of the induction heating system consists of the equivalent inductor and the internal resistance series of the iron pot itself.Its coupling with the original edge circuit can heat the drinking water and food in the car,the design device brings convenience to people's life,improves the quality of life of the people in the car,has great application value.In this thesis,the LCL-type primary edge resonance topology suitable for two different systems is determined,based on the circuit equivalent model,the output power and transmission efficiency of the two systems are derived,and the influence of the original edge coil inductor and the inductive ratio and quality factors on the transmission characteristics of the two systems is analyzed,which provides the basis for selecting _rL?_PL andC_P parameters of the LCL loop.Secondly,the parameters of each system are calculated to meet the output power and transmission efficiency index requirements of each system.The hardware circuit design is carried out,including the main circuit,the drive circuit,the control circuit,the magnetic coupling mechanism.Finally,a simulation model and experimental prototype are constructed,the output power of the wireless energy transmission system is 10 W,the output power of the induction heating system is 35 W,the main parameters of each system are detected and analyzed,and the influence of transmission distance on the output power and efficiency of the wireless energy transmission system is studied by experiment.The experimental results verify the correctness of theoretical analysis and the feasibility of the design scheme.
