Aiming at the shortcomings of the traditional contact power supply mode, a low-power magnetic coupling resonant wireless power supply system was designed to study the transmission characteristics of the system. The circuit coupling theory is mainly used to establish the equivalent circuit model of the system. The influence of system parameters on the transmission characteristics, including the resonant frequency, load resistance and coupling coefficient, is simulated by MATLAB. Finally, a low-power wireless power supply system test platform is built. The transmission characteristics of the system were tested and verified. The transmission characteristic test results are in good agreement with the MATLAB simulation analysis results, indicating that the designed low-power magnetic coupling resonant wireless power supply system can perform good wireless energy transmission, and also provide new ideas for the development of low-power wireless charging equipment. |
