In a switch mode power supply the input is fed from an alternating source, rectified, and filtered to obtain unregulated DC voltage which is further pass through a regulator to obtain a regulated Direct current, thus using it as a DC-DC converter. In this work, a Photo-voltaic panel is used to obtain Direct current which is fed to the hardware model, with a sole purpose of increasing dependencies on Renewable Energy sources, which is not only cost-effective but useful at places where a conventional current is not available.
