[Abstract]:Radio energy transmission, as a new technology, can solve the problem of metal conductor contact in traditional electrical system, enhance the sensitivity of the system and make the system more secure. Nowadays, the bidirectional transmission technology of radio energy is gradually mentioned, which satisfies the requirement of bidirectional energy transmission through bidirectional topology. In the mobile phone charger, electric vehicle and so on, the electric energy bidirectional transmission technology will greatly enhance its flexibility. Depending on its unique advantages, the technology will be widely used in all aspects of people's production and life in the near future. In this paper, the background and present situation of radio energy transmission technology are summarized, and the relevant hot issues of radio energy bidirectional transmission technology are introduced, and the fields in which this technology can be used are analyzed. In addition, the classification of radio energy transmission technology is simply analyzed: the wireless transmission mode of magnetically coupled resonant electric energy is analyzed, and the circuit simulation model is established for the simple harmonic vibration topology in series. Saber circuit simulation software is used to analyze the waveform of the transmission, receiving coil and load of the string / string topology. The three-dimensional model of the system was built by using the finite element analysis software Maxwell. The shape of different coils was compared and the optimal coil structure was determined. Finally, the three-dimensional model simulation of the system is realized by calculating the coil inductance and resonant capacitance, and the final simulation data are obtained. In this paper, the hardware circuit of radio energy transmission system is designed and the final experimental model is constructed to verify the experimental conclusion. The hardware circuit mainly includes: DSP simulator, switch drive circuit, high frequency inverter circuit, transmitting and receiving coil, rectifier circuit, etc. The design ideas and implementation steps of each part are introduced and analyzed, and the parameters of the device are set up. The experimental platform of radio energy bidirectional transmission system is constructed. When the distance between coils is 3 cm, the maximum transmission efficiency of the whole system is about 42%. Finally, the optimization of the transmission power of the system is studied. By analyzing the coil size, the optimization of the inverter circuit and the penetration of the system, the method of optimizing the output power of the system is obtained, which improves the stability of the system.
