Abstract


In this paper, couple of non-isolated high gain multi-input DC-DC converter (MIC) topologies are presented and their salient features are compared. Each of the high gain MICs are synthesized from two identical high gain (HG) DC-DC converter structures. The input power supply to each of the MIC topologies comprising of two parallel connected HG converters is obtained from two separate sources. The individual outputs of the two HG converters are connected in parallel with each other through ORing diodes and deliver the required load power. The individual HG converter is developed from an interleaved boost converter (IBC) configuration. Its voltage gain is enhanced by judiciously adopting hybrid combination of various gain extension techniques like (i) coupled inductors, (ii) voltage-lift technique and (iii) voltage multiplier cells. The presented MIC topologies yield a voltage gain of about 10.33 and 21.11 at 200W power level. Moreover, experimental results demonstrate the power sharing concept of both the MICs when both the input sources are available. In addition, the ruggedness of the proposed MIC structure is clearly validated through the experimental results obtained when only one source supplies the load.
