[Abstract]:With the rapid development of science and technology, people have made great progress in various fields. With the increasing global demand for electricity, the disadvantages of traditional transmission methods are gradually exposed. The radio energy transmission technology has been developed and has been used in many fields. At present, the radio energy transmission technology still has a lot of research space, including the synchronous transmission technology of signal and electric energy. Electromagnetic compatibility and so on. From the point of view of stable and reliable signal synchronous transmission technology, this paper designs the structure of inductive radio energy transmission system, and studies the loosely coupled transformer. This paper analyzes the structure of inductive radio energy transmission system, divides the system into four parts from the point of view of circuit function, compares and analyzes the advantages and disadvantages of the common topologies of each part in turn, and studies the characteristics of the four basic compensation structures. The output characteristics of the system voltage and current under the series compensation structure are summarized, which lays a foundation for the following research. Secondly, four typical synchronous signal transmission techniques are analyzed in detail in this paper. Combining with the topology of inductive radio energy transmission system, the feasibility of changing compensation capacitor for signal transmission is analyzed theoretically. After considering three modulation and demodulation modes, A synchronous transmission scheme of signal and electric energy based on changing resonant capacitance is designed. The working mode of the circuit is analyzed in detail, and the hardware design of the system is described from the point of view of design idea, parameter selection and so on. This paper optimizes the design of signal transmission channel-loosely coupled transformer. First, the modified magnetic circuit model is established for EE type loosely coupled transformer with magnetic core, and the optimum value of the width of circular coil is obtained by calculation. Then the Ansoft finite element analysis tool is used. The parameters such as coil size, width and the number of magnetic core structure are simulated and analyzed. The simulation results verify the correctness of the theoretical analysis, and determine the objective and direction of the optimal design of loosely coupled transformers. In this paper, Cadence Pspice analysis tool is used to simulate and verify the synchronous transmission technology of signal and electric energy of inductive radio energy transmission system, to observe the waveform of each point, to optimize the parameters and to build the experimental platform. According to the theoretical analysis and simulation results, the effect of the inverter midpoint voltage and current, load voltage, load constant voltage output characteristics and signal bidirectional transmission and extraction technology are verified, and the ideal results are obtained.
