The invention discloses an unmanned aerial vehicle redundant power supply device. The unmanned aerial vehicle redundant power supply device comprises a power module with dual branches of lithium battery inputs and for supplying power for a GPS, an automatic pilot and a data transmission and image transmission apparatus, a power management module connected with the power module and used for controlling voltage input sources so that the two input sources can be backups of each other, regulating a resistance proportion value to use a standby power source for undervoltage protection of a main power source, and recovering the switching function of the main power source to meet redundant design, and a digital steering engine voltage module connected with the output of the power management module and used for realizing voltage-stable filter output of the power source by use of a DC-DC integrated synchronous step-down controller and providing a digital steering engine with a working voltage. The device is simple in structure; two battery packs are taken as the input voltage sources; the redundant design and different equipment power supply requirements are met by use of a related integrated power management chip and the DC-DC integrated synchronous step-down controller; as a result, high stability and reliability are achieved.
