POWER ELECTRONIC TECHNOLOGIES IN RENEWABLE ENERGY SYSTEMS

For supplying the demand of global electrical energy two major technologies will be important in future. First is to modify the electrical power generation sources from the traditional energy sources to renewable energy resources and the second is to use highly efficient power electronics circuits in power generation, power transmissi on and power distribution and end - user utilities. This paper discuss the some of the emerging renewable electric energy sources, which by using power electronics technologies are modifying renewable energy sources to work as important power so urces in the electric energy system that will play very important role as future energy supplies in distributed generation. Power electronics technologies has got maturity after several years of dynamic development of power electronic components, converters, pulse width modulation techniques, electrical machines, electric motor drives, modern control, and simulation techniques. In the twenty first century, we expect to see the tremendous effect of power electronics not only in worldwide industriali zation and energy systems, but also in energy conservation, renewable energy systems, an d electric vehicles .
