The invention relates to a circuit
system of a multi-rotor unmanned aerial vehicle FCS and a
power management method thereof, and relates to the field of
fuel cells and unmanned aerial vehicles. According to the circuit
system of the multi-rotor unmanned aerial vehicle FCS and the
power management method of the circuit
system, the problem of matching of a multi-
voltage platform circuit system architecture when a
hydrogen fuel
cell system and the unmanned aerial vehicle are integrated is solved, and a more reasonable
power management control method is provided to realize safe, accurate and efficient control of the system. Specifically, a part power supply mode of a multi-
voltage platform is provided, the
power supply voltage is stable, and
model selection and platform design of system parts are facilitated; the power supply of the parts of the multi-
voltage platform can be independently controlled, and the control can be completed by selecting the buck-boost power
supply management module or the controller FCU, so that the power
supply management of the parts is facilitated; the voltage platforms are powered on step by step and self-checked step by step, the
fault probability is reduced, the service life of parts is prolonged, and the range of possible reasons of faults can be further narrowed conveniently through step-by-step power-on.
