A novel hybrid interleaved DC-DC converter for micro grid application.

In recent days there is an increase in the need for suitable converters for renewable energy applications. This proposed work deals with a novel non-isolated hybrid DC-DC converter topology for renewable applications like Solar Photovoltaic (PV). To lessen the input current ripple, the suggested converter is built using a Layered boost converter (LBC) concept and this proposed approach becomes hybrid interleaved converter (HIC). By (i) applying the voltage lift technique and (ii) swapping out the traditional inductors present in the Linked Inductors (LIs) with the proper turns ratio which will be coupled to the LBC, and in the LIs' secondary side a voltage converter cell (V_CC) is connected. By considering that the voltage gain is primarily extended at the secondary side, low voltage stress of 12.63% of the output voltage, is functional to the LIs and switches. The proposed converter produces a 15.83% high voltage conversion ratio. The experimental set up has been designed for the rating of 500 W. Results from an experiment using a 24 V/380 V, 225 W initial converter functioning at 91.6% efficiency provided as evidence that the proposed paradigm, was used to produce a high voltage conversion ratio of 15.83 with a minimal input current ripple (20%).
