Renewable energy applications have become a focal point of most researches in recent years to achieve an eco-friendly atmosphere and mitigate the dangers posed by global warming and climate changes. A modified high gain DC-to-DC Ćuk converter using voltage lift technique is presented in this paper. The converter generates an amplified version of the input voltage through the inclusion of a switched capacitor topology. In perspective view, the resultant modified Ćuk circuit generates a voltage conversion ratio of twenty at duty ratio of 0.9 by using 3 inductors, 5 capacitors and 4 diodes. A detailed analytical analysis is validated by simulations conducted in Matlab/Simulink. MODIFIED (2/1-K) OUTPUT GAIN ĆUK DC-TO-DC CONVERTER CIRCUIT FOR RENEWABLE POWER APPLICATIONS
