Design and Performance Analysis of Power Management System for Multi-rotor UAVs

The power management system of the operational multi-rotor Unmanned Aerial Vehicles (UAVs) is designed and optimized with a high degree of integration, which can input one 4S or 6S battery and output 10 voltages, including two 12 V/5 V stable voltage outputs, to meet the flexible power supply of various loads. In addition, the upper computer of the system is also enough to monitor the flight status of the drone and provide PWM/CAN control mode and a variety of safety parameter settings to ensure the flight safety of multi-rotor UAVs. Experimental results show that the system studied in this paper meets the design requirements and has reliability.
