The invention provides a power supply circuit and a power supply device of an unmanned aerial vehicle, the power supply circuit of the unmanned aerial vehicle comprises a battery detection module, a slow start module and a restoration module, the input end of the slow start module is used as the input end of the power supply circuit of the unmanned aerial vehicle, and the output end of the slow start module is connected with a load input capacitor. The restoration module is connected with the slow start module, the detection end of the battery detection module is connected with the input end of the slow start module, and the output end of the battery detection module is connected with the control end of the slow start module and the control end of the restoration module. When the power supply battery is disconnected, the equivalent resistance value on the power supply circuit is reduced to the maximum value through the reduction module, so that the charging current to the load input capacitor at the moment when the power supply battery is connected is ensured to be minimum, and meanwhile, the equivalent resistance value on the power supply circuit is limited by the slow start module, so that the charging current is prevented from being suddenly increased, and the service life of the power supply battery is prolonged. Therefore, the electric spark phenomenon is avoided and the circuit safety is ensured.

    本发明提出一种无人机的供电电路及供电装置,无人机的供电电路包括电池检测模块、缓启动模块以及还原模块,缓启动模块的输入端作为无人机的供电电路的输入端,缓启动模块的输出端与负载输入电容连接,还原模块与缓启动模块连接,电池检测模块的检测端与缓启动模块的输入端连接,电池检测模块的输出端分别与缓启动模块的控制端以及还原模块的控制端连接。通过设置还原模块来使得在供电电池断开接入时,将供电线路上的等效阻值还原为最大,从而保证在供电电池接入瞬间的对负载输入电容的充电电流最小,同时缓启动模块限制在供电线路上的等效阻值大小,从而防止充电电流突然增加,进而避免出现电火花现象,保证电路安全。
