This thesis describes the design, simulation, implementation, hardware bring-up, software debugging and detailed testing of a stabilised adjustable switch-mode power supply intended for universal use. The power supply consists of two stages: the first reduces and rectifies the mains voltage, while the second stage regulates the output voltage and current using digital control. Three fully floating channels were designed, including an electronically controlled output switch and a control panel. Each channel can supply 0 to 35 V and 0 to 6 A (tested up to 22,5 V/5 A, 30 V/2,5 A), which was verified by detailed measurements.
