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 buildinga functioning prototype that balances various requirements while maintaining a reasonablecost. The project involves detailed hardware design, simulation, prototype production, andtesting.A theoretical review and comparison of suitable converter topologies are performed, andthe Flyback converter design is explained. The hardware design section covers the selectionof components, their functions in the circuit, and the printed circuit board (PCB) layoutconsiderations.The design is produced and built. The troubleshooting process is laid out, and several testsare performed and discussed to evaluate the prototype.
