Unmanned Aerial Vehicle (UAV) frequently encounter various external disturbances during flight. After experiencing such disturbances, the UAV’s power supply must quickly respond and maintain stable output. To address this problem, this paper proposes an improved active disturbance rejection control (IADRC) scheme combined with peak current mode control (PCMC) based on a six-phase interleaved parallel synchronous buck converter. Modal analysis was conducted on the synchronous buck converter, and small-signal modeling was performed under current control mode to analyze closed-loop stability. The dynamic response speed was improved by utilizing a peak current inner loop, enabling precise current sharing. The system’s disturbance rejection capability was enhanced by employing an improved extended state observer for real-time estimation of disturbances. This approach offers advantages such as high dynamics, strong disturbance rejection, and good current sharing. Finally, an experimental prototype with a rated power of 1000 W, maximum efficiency of 96.9%, and power density of 12.9 W/cm² was constructed. Comparing three different control schemes, the response waveforms of the prototype verify the feasibility and advancement of the scheme in this paper.
