Design and analysis of a resonant inverter fed from a Cûk converter for the conversion of alternative energy directly into commercial supply efficiently

Power crisis in the world has compelled mankind to think for alternative energy. But all the alternative sources have not yet been exploited. From many ongoing researches, it reveals that if all the alternative energy sources are exploited, the energy crisis of the world would be reduced to a great extent. Many alternative energy technologies today are well developed and they are reliable and cost competitive with the conventional fuel generators. There are many alternative sources of energy such as biomass, wind, solar, minihydro and tidal power. The most important advantage offered by alternative energy sources is their potential to provide sustainable electricity in areas not served by the conventional power grid. Most of the alternative energy technologies produce DC power, and hence power electronics and control equipment are required to convert the DC power into AC power. Industry professionals are now opening their minds to alternate energy sources that can deliver quality power at reduced life-cycle costs in a variety of applications. Alternate energy sources generate power independently of the electrical grid. These sources can operate in stand-alone mode or they can be interconnected directly to the grid. With the use of power electronics, the alternative energy may be directly converted into commercial supply effectively in a cost effective way.
