PROJECT 03 / POWER ELECTRONICS
Drone Power Board
A power distribution board with independent primary and backup supply paths for a drone.
01 / OVERVIEW
Power with a backup plan
This four-layer PCB was designed to manage a primary power path and an independent redundant backup supply. A controlled soft-start mechanism pre-charges the high-capacitance loads in the motor controllers to limit inrush current on startup.
Key design elements
- Two independent power supply paths: primary and backup
- Soft-start by pre-charging motor controller loads
- Inrush current limitation during startup
- STM32-family microcontroller for voltage monitoring and power management
- Communication with the drone control system
