A Non-Isolated Extendable Common Grounded DC-DC Boost Converter for DC-Microgrid Applications

The DC-DC high step-up converters are vital sectors for interconnecting renewable energy sources to DC micro-grids and achieve to proper values of voltage for DC buses. A DC-DC non-isolated single switch converter is suggested in this paper. Being extendable while supplying common grounding feature are prominent exclusivities of this structure. The operation of the topology in continuous conduction modes is assessed and presented. The performance of the DC-DC boost converter is evaluated by comparing with similar other topologies. Moreover, dynamic performance is investigated. The accuracy of the presented topology is affirmed by simulating it using PSCAD/EMTDC.
