چکیده
The output voltage obtained from renewable energy sources is low and needs to be stepped up by and order of 20 for practical usage or grid integration.This emphasizes the need for high gain DC-DC converters. The proposed DC-DC converter topology combines the simple boost converter and a coupled inductor with voltage double stages to provide high voltage gain. The main advantages of this topology are continuous input current, large conversion ratio without extreme duty. The proposed converter is simulated and the waveforms obtained. The experimental setup will be taken up as future work.
