Abstract: Now a day, lot of power shortages is to be observing over the world especially country like India. Also the power generated from fossil fuels are becoming so less. The fossil fuels used like coal, lignite, oil and gases. So due to its uneconomical and hazardous to environment, the renewable based energies like solar, wind, biomass, tidal etc. are to be used , which does not cause any pollution to the environment. In this paper the simulation and analysis of boost converter design and simulation also performed. Here in this paper, the input voltage to the boost converter is given as 12 volts and receives output voltage 25 volts.

Keywords: Step up DC-DC converter, photovoltaic system, solar energy, Spice software.
