Introduction:
This project is a power supply of 12v and 2amp which is required for the solar panal having 40watt rating.At vigyan ashram we are required to get a power from the solar panal for various types of light applications.The voltage getting from the solar panal is of constant 20v and current is 2amp.So this voltage needs to be convert in to the required one which is in this case 12v and 2amp.So we designed a small circuit in the fablab using the modela machine and the pcb is tested for the same.This is running very fine for solar panal.The following is the circuit diagram of the project.
