Coupled Inductor Based Radio Energy Transmission Circuit

摘要

The wireless energy transmission based on coupled inductor is a new type of power transmission technology, which can overcome many shortcomings of traditional power transmission methods. This technology can provide strong support for the further development of modern society and bring great convenience to people's lives. Therefore, research on the coupling energy-based radio energy transmission circuit will have important academic significance and practical value. This paper first introduces the development history of radio energy transmission technology and the current development. Then, the paper analyzes the circuit structure of the wireless energy transmission system based on inductive coupling in detail, studies its working principle, uses the mutual inductance model to model the circuit of the wireless energy transmission system and calculate the relevant transmission efficiency. In the circuit modeling process, the selection and calculation of the compensation capacitor is studied emphatically, and further parameters are calculated for the circuit after the compensation is improved. After that, this paper studies the characteristics of the magnetically coupled resonant radio energy transmission method in detail, and focuses on the difference and connection between the magnetic coupling resonant type and the inductive coupling type.
