Power supply requirements of new generation microprocessors are one of the problems of latest generation. New generation microprocessors require 40-100A and voltage in the range of 1 V or 2 V. Lower voltages can be obtained from DC-DC converter namely the buck converter. The three phase DC-DC converter of 100W, 12V/1V with efficiency 97% is modeled. With the help of soft switching techniques, this multiphase technology gives excellent transient response and increased efficiency. The input to the DC-DC converter is provided from a hybrid combination of wind and solar system. Owing to the present scenario of the fuel-crisis, renewable energy sources are explored to a greater extent. Renewable energy sources being environment friendly are called as Green Energy Sources.

In parallel to developing technology, demand for more energy makes us seek new energy sources. The most important application field of this search is renewable energy resources.Wind and solar energy have been popular ones owing to abundant, ease of availability and convertibility to the electric energy. We will focus on Modeling the design and verification process for Renewable and Green Energy sources.Samples like solar,wind and tidal energy are used for making model.The term Green energy can be associated with environment-friendly Generation,transport,storage and control of electrical energy .Solar power,wind power and the natural flow of water are resources that comply with our definition of Green Energy.Since the natural fossil energy resources are limited on this planet,we have to put our focus on green power generation like solar and wind power.
