Abstract
In this paper, two-input integrated dc-dc converter analysis and control strategies useful to photovoltaic (PV) applications is presented. This dc-dc converter is basically combination of individual buck and buck-boost converters supplying for a common dc bus. Here one inductor is sufficient enough for power conversion in both the converters. Buck-boost converter, with maximum power tracking, eradicates the complete power from the PV source and supplies to the load, while the remaining load power demand is drawn from the stand-alone dc source, which is equipped with single-loop voltage-mode controller for dc bus voltage regulation. Closed-loop converter performance of this converter is simulated and compared with the theoretical calculations. Simulation studies are presented here for constant resistive and battery type of loads. The load power distributions among the sources are proved.
