Project Overview The goal of this diploma thesis was to design and implement a motor-controlled XY positioning system for the measurement of an ionizing radiation field. The project partner SL required a setup capable of moving a field strength measurement probe precisely across a two-dimensional grid. A mechanical XY linear guide with stepper motors was provided by the partner — the focus of the project was the development of a complete electronic control system and a software interface to enable command-based operation. ...

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. ...
