A Novel High StepUp DC DC Converter Based on Integrating Coupled Inductor and Switched-Capacitor Techniques for Renewable Energy Applications

ABSTRACT

In this paper, a novel high advance up dc/dc converter is displayed for sustainable power source applications. The proposed structure comprises of a coupled inductor and two voltage multiplier cells, so as to get high advance up voltage gain. What’s more, two capacitors are charged amid the turn off period, utilizing the vitality put away in the coupled inductor which builds the voltage exchange gain. The vitality put away in the spillage inductance is reused with the utilization of a latent clasp circuit. The voltage weight on the fundamental power switch is additionally decreased in the proposed topology. Subsequently, a fundamental power switch with low opposition RDS(ON) can be utilized to decrease the conduction misfortunes. The activity guideline and the relentless state examinations are talked about altogether. To check the execution of the exhibited converter, a 300-W lab model circuit is actualized. The outcomes approve the hypothetical examinations and the practicability of the exhibited high advance up converter.

 CONCLUSION

This paper shows another high-advance up dc/dc converter for sustainable power source applications. The recommended converter is appropriate for DG frameworks dependent on sustainable power sources, which require high-advance up voltage exchange gain. The vitality put away in the spillage inductance is reused to enhance the execution of the exhibited converter. Besides, voltage weight on the primary power switch is decreased. Accordingly, a switch with a low on-state obstruction can be picked. The enduring state task of the converter has been dissected in detail. Additionally, the limit condition has been acquired. At long last, an equipment model is executed which changes over the 40-V input voltage into 400-V yield voltage. The outcomes demonstrate the plausibility of the introduced converter.
