The invention provides a power management circuit applied to a solar unmanned aerial vehicle. The power management circuit comprises a power management main control board, a solar cell and a super capacitor module. The power management main control board comprises a plurality of pins. The solar cell supplies power to the power management main control board through voltage reduction of the linear voltage regulator, and when the power supply voltage of the solar cell to the power management main control board exceeds a threshold value, the linear voltage regulator plays a protection role. The super capacitor module is coupled with the power supply management main control board, the super capacitor module supplies power to the power supply management main control board, and under the condition that the solar unmanned aerial vehicle needs high-power output, the power supply management main control board performs current and voltage acquisition functions and can synchronously display data values of current and voltage at a specific moment. According to the power supply management circuit provided by the invention, the super capacitor module is combined, so that in order to ensure constant power output after voltage boosting and voltage reduction of the circuit, solar energy and a super capacitor are adopted for two-way power supply, and high-power output of the unmanned aerial vehicle under special requirements can be met.
