Development of Digital Laboratory Power Supply

This paper presents a complete design and development of a digital laboratory power supply block that can provide stabile voltage supply in the range from 0 to 20.48V. The design process includes development of the block diagram, schematic and a Printed Circuit Board. The functionality of the circuit was successfully verified. The design approach represents an embedded system that utilizes Atmega microcontroller. The solution offers high precision digitally controlled laboratory power supply.
