Methods/Statistical analysis: In this paper the bidi- rectional dc-dc converters and the three port dc-dc converter simulation results are obtained and investigated using MAT- LAB and PSIM software. Experimental procedure validate the results Findings: Two dc-dc converters bidirectional capabil- ity and different storage element placement is considered for analysis and their performance is analysed and from the ca- parison a feasible converter for three port dc-dc converter is derived and considered for analysis. This converter con- sidered for analysis can be operated in both buck and boost modes of operation. Improvements/Applications: The three port con- verter is proficient for energy diversification from two energy sources individually or simultaneously. This three port con- verter finds a suitable place in satellite applications. 1 International Journal of Pure and Applied Mathematics Volume 118 No. 17 2018, 435-448 ISSN: 1311-8080 (printed version); ISSN: 1314-3395 (on-line version) url: http://www.ijpam.eu Special Issue ijpam.eu 435
