Due to deficiency of the earth’s fossil energy resources such as oil, gas, coal, etc. The production rate is getting deflated every year. Considering this scenario into account it is expected that the usage of the resources may exceed the production rate in the next decades, in turn the price of energy resources will obviously rise. It is necessary to meet the demand by alternative energy sources (renewable) like solar, wind, geothermal etc. Among the renewable energy resources, wind power is gaining momentum not only as a means to reduce the CO2 emissions but also as an interesting economic alternative in areas with appropriate wind speeds. The nature of the wind is intermittent due to varying behavior of the environment. Therefore, the power produced by such wind turbine will also vary and injection of such power can bring new challenges when it is connected to the grid. In this proposed scheme, the design of miniature wind mill reduces the cost as well as the space required to install .This miniature windmill is integrated with the grid to meet the energy demand in household .In this scheme the generated wind power can be extracted under varying wind speed and can be stored in batteries at low power demand hours, here the inverter control using MOSFET to achieve the faster dynamic switchover for the support of critical loads. The permanent magnet DC generator is used to drive the wind turbine to generate output voltage. By the use of power electronics circuit arrangement the voltage is generated to meet energy demand.
