摘　　要：针对平流层艇载风速计电滑环供电方式的不足,设计了基于DSP控制的艇载风速计非接触供电系统。利用电磁感应原理,明确了非接触供电系统的组成;通过建立系统等效电路模型,分析了影响系统传输效率及传输功率的因素;结合艇载风速计的结构及应用背景,借助ANSYS Maxwell电磁仿真软件设计了嵌套式松耦合线圈。通过对系统主要电路进行仿真并搭建基于DSP控制的原、副边电路,对系统的工作特性进行验证,仿真及试验结果表明:基于DSP控制的平流层艇载风速计非接触供电系统能够实现良好的非接触能量传输,降压后可为平流层艇载风速计供电。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.
