A DC-DC interleaved forward converter to step - up DC voltage for DC Microgrid applications

DC Microgrid is highly penetrated by various DC-DC power converters for a proper management. Several technologies of DC-DC power converters have been experienced for reaching a suitable topology of converter systems providing high performances of DC Microgrid distribution. The concepts of these systems are based on the circuits capable to provide; easier connection between Microsources and DC Microgrid, stability of DC Microgrid bus, input output current ripples cancellation, galvanic isolation, power loss reduction, high ratio conversion and high switching scale for output filter size reduction. This paper presents models of DC-DC Forward converters leading to the suitable topologies. Precisely, the combination related to cascaded, paralleled, bridged and interleaved technologies of classical DC-DC Forward converters have been experienced for being applied to DC Microgrid. Interleaved DC-DC Forward converter with double three windings transformer is analyzed under PSPICE simulation for validating the high conversion issue and clamped regenerative techniques.
