Designing and building a low power, dual output, isolated power supply for use in infrastructure components

Abstract

The goal of this project is to gain competence in low-power power supply design by building a functioning prototype that balances various requirements while maintaining a reasonable cost. The project involves detailed hardware design, simulation, prototype production, and testing. A theoretical review and comparison of suitable converter topologies are performed, and the Flyback converter design is explained. The hardware design section covers the selection of components, their functions in the circuit, and the printed circuit board (PCB) layout considerations. The design is produced and built. The troubleshooting process is laid out, and several tests are performed and discussed to evaluate the prototype.
