Conventional power generation has some limitations such as very costly production cost, heavy transmission & distribution loss, limited reach, big threat for environment & public health global warming, greenhouse effect, acid rain Etc. To overcome these limitations we can use renewable energy sources like wind, tides, solar, geothermal heat, and biomass. In this paper I am using solar energy source. Solar energy source generate small amount of DC power, to step up this small amount of DC power I am using PE converters Like DC/DC step-up boost converter. This paper presents a Modeling Analysis and Control of a DC/DC Boost Converter. Power for the boost converter can come from any suitable DC sources such as batteries, solar panels, rectifiers and DC generators. A boost converter is a DC to DC converter with an output voltage greater than the source voltage. This system has a nonlinear dynamic behavior, as it work in switch-mode. In this paper I analyze the equations of a boost converter and propose a design components, simulation and modeling of DC/DC boost converter.
