Partially Isolated Four Port Dc Dc Converter for Renewable Energy Harvesting in Dc Microgrid

Abstract

The search for alternate energy sources to meet the increasing energy newlinedemand and the fast depleting carbon fuel resources resulted in a gradual transition newlineof conventional centralised power generation units to distributed power generation newlineunits which relays on renewable energy sources. Microgrids are developed as an newlineinterface for connecting locally available energy sources to the local loads in newlinedistributed generation systems. The existing microgrids operate mainly on the AC newlinepower distribution principle. But most of the renewable energy resources are DC newlinepower source generators and most of the modern devices work on DC power. Hence newlineconverting DC power to AC for connecting to the microgrid and again to DC power newlinefor supplying the load increase the losses and reduces the efficiency newline
