Hybrid Energy Source is used to combine the multiple energy source, in order to use their characteristics at their best. A power electronic converter is needed to interface these hybrid energy source with a load. In traditional methods various single input DC-DC power electronic converters are used but it has drawbacks such as, complex design, huge cost and less efficiency. Therefore, it is important to identify the opportunities to cutdown the cost and to enhance the performance of the converter. One such possibility is to use dual source DC-DC converter that leads to reductions of filter size, cost and losses. Taking this into consideration, this study explores, the various topologies of dual source DC-DC converters and compares their performance for different operational conditions. The converter can work in buck, boost and bidirectional operating mode to achieve desired voltage level. Furthermore, various converter’s performance is compared in terms of component counts, efficiency, output voltage vs duty ratio, average output power vs output resistance.
