The invention provides a power supply device, a control method and an unmanned aerial vehicle, the power supply device comprises a bus bar, a first power supply, a power supply controller, a switch device and a backup battery, and the bus bar is connected with an electricity load and is used for supplying power to the electricity load; the power supply controller is electrically connected with the first power supply and the bus bar, the power supply controller comprises a voltage conversion module, and the voltage conversion module is used for converting the voltage of the first power supply into a target voltage and outputting the target voltage to the bus bar; the switch device is electrically connected with the bus bar, the power supply controller and the backup battery; and the power supply controller is used for controlling the switching device to be switched on, so that the backup battery outputs the target voltage to the bus bar when the voltage conversion module fails. The problem that once a DC/DC conversion module adopted for power supply of an existing unmanned aerial vehicle breaks down, the unmanned aerial vehicle loses power supply and is in a dangerous state is solved.
