BLDC - Electronic speed controller
Project Overview The objective of this project was to design and develop an extremely compact Electronic Speed Controller (ESC) for drone propulsion systems. The primary goals were size optimization, high efficiency, and flexible motor-control capability, suitable for integration into lightweight aerial platforms. Technical Concept The ESC architecture was based on three half-bridge stages using high-performance Power MOSFETs to minimize conduction and switching losses. An Infineon gate driver IC with an integrated charge pump was selected to drive the bridge transistors efficiently, ensuring stable high-side switching without additional bootstrap components. The control logic was implemented on an STM32 microcontroller, chosen for its computational performance, PWM precision, and integrated ADC features. ...
