In this paper, a new non-isolated high voltage gain hybrid dc-dc converter for dc micro grid applications has been proposed, which utilizes both the switched inductor (SI) and switched capacitor (SC) technique to attain a high gain.Abstract:
This paper deals with a new non-isolated high voltage gain hybrid dc-dc converter for dc micro grid applications. The proposed converter utilizes both the switched inductor (SI) and switched capacitor (SC) technique to attain a high gain. The suggested voltage lifting mechanisms result in reduced voltage stress on switches (about 45% of the output voltage) and diodes. A hardware prototype of 380V/120Watts is developed in laboratory and presented here. Experimental results and a brief comparison with other high gain converters included in the paper, confirms the capability of the proposed converter to provide high voltage gain at very low duty cycle with low voltage stress on switches and diodes used.read more
