Abstract: A two input boost stage power electronic DC-DC converter with high voltage gain is put forward. From the input sources, a continuous current is being drawn using proposed topology. Using the proposed converter it is easy to attain a gain of 20 along with the advantage of drawing continuous current from input. The procedure for selection of components and design of components for the proposed converter is described. The suggested converter with V_in=20,V_out =400V and power rating 400W is verified by simulating in MATLAB.

Keywords: renewable energy source, boost converter, high voltage gain, voltage multiplier stage.
