ABSTRACT
This article presents an improved model of a high voltage gain DC-DC converter topology. The voltage gain of the proposed topology is extended using a newly structured cascaded boost converter with voltage doubler cells along with the Super Luo structure in the network. The ultimate aim is to improve the output voltage gain of the proposed converter to a higher level with a lower duty cycle. Additionally, the design considerations minimize the voltage stress of the components (diodes, capacitors, and semiconductor switches) compared to the conventional topology. Moreover, the proposed topology ensures a continuous input current to the structure. Mathematical modeling is developed using steady-state analysis, and the results are analyzed using the MATLAB/Simulink. Finally, the proposed converter provides a high gain, that is, 10, at a lower duty cycle of 0.32 with reduced voltage stress on the components.
