This thesis presents the development of a portable adjustable power supply adaptable to varying electrical network conditions. The proposed design is based on a buck-boost DC-DC switching converter, which provides a wide range of output voltage regulation. A control system has been implemented using an STM32 microcontroller with a digital PI controller. Additionally, a measurement subsystem and a data transmission subsystem based on IoT technologies (ESP32, MQTT) have been developed. The system performance was evaluated through simulation in the Matlab/Simulink environment, and its dynamic characteristics were analyzed. The obtained results confirm the effectiveness of the proposed solutions.
