[Abstract]:In this paper, a low frequency radio energy transmission system is designed. The output power of the system is 3kW, the maximum system transmission efficiency is more than 80, the wireless transmission distance is 8cm-10cm, the working frequency is less than 10kHz. The basic theory of radio energy transmission system is deduced and analyzed in this paper. The corresponding formula is obtained by using the mutual inductance coupling model. The effective distance under the Leeds line is calculated according to the requirement of increasing the transmission distance, and the corresponding formula is obtained. The effect of the parameters on the effective transmission distance is analyzed. Through theoretical calculation, we can better understand the key of the design of radio energy transmission system and effectively guide the construction of the actual system. According to the need of the system, the low frequency radio energy transmission system is designed. The digital control chip is used to adjust the frequency of the system, and the full-bridge inverter circuit is used to improve the efficiency of the system. Because of the low operating frequency and high output power IGBT is selected as the switch device of the full-bridge inverter circuit with proper driving module and peripheral buffer circuit. Besides the design of weak current part, every part of wireless transmission part with power is analyzed. Through the comparison of capacitance and linear material, the capacitance type and conductor material of winding inductance are determined. The coil turns are simulated by using the simulation software according to the changing trend of coupling coefficient, and the circuit simulation is done to get the effect of the inductance of the primary and secondary edges on the power and efficiency of the system. The optimal inductance of primary and secondary edges is obtained, and the system performance is greatly improved. The load is determined by simulation, and the load size is determined by the result of simulation curve without frequency bifurcation. In order to compare the characteristics of the system with different natural frequencies, this paper simulates the system with different inherent frequencies under PSSP structure and PSSS structure, and obtains the three dimensional figure of power efficiency of each system. According to the analysis of each system and the comparison of each system as a whole, the change trend of the system with the change of natural frequency can be obtained. According to this conclusion, the coupling coefficient and load are further simulated. The influence of coupling coefficient and load on radio energy transmission system is obtained. In view of the inconvenient operation of the actual experiment, the paper also simulates the initial vibration of the system, and obtains the starting waveform of the current to ensure the security of the system. At the end of this paper, the parameters of the actual system are given, and the characteristic experiments of the system are carried out, including the booster experiment at different distance, the frequency sweep experiment, the variable load experiment and the further shift transmission experiment. The basic characteristics of the system are obtained. In addition, the corresponding experimental curves and analysis results are obtained by changing the natural frequency of the system and conducting experiments.
