| Abstract: | In view of the deficiency of the power supply mode for the electric slip ring of the stratospheric airship anemometer, a contactless power supply system of the airship anemometer based on DSP control is designed. Based on the principle of electromagnetic induction, the composition of contactless power supply system is defined; by establishing the equivalent circuit model of the system, the factors affecting the transmission efficiency and power of the system are analyzed; combined with the structure and application background of the boat borne anemometer, the nested loosely coupled coil is designed with the help of ANSYS Maxwell electromagnetic simulation software. Finally, the main circuit of the system is simulated, and the primary and secondary circuits based on DSP are built to verify the working characteristics of the system. Simulation and experimental results show that the designed contactless power supply system can accomplish good wireless energy transmission, and can supply power for stratospheric shipboard anemometer after depressurization. |
