Design of a Multi-Input Single-Output DC-DC Boost Converter for Micro Grid Application

Abstract

This paper proposes a Multi-Input Single-Output (MISO) non-isolated DC-DC boost converter. The converter integrates various sources to a single DC bus making it applicable for inverter interfacing. The load power can be apportioned amongst the input sources. A single inductor is used in this topology that makes it light weight and less expensive. Depending on the charging and discharging state of storage component, two different modes of operation are explained in this paper. The theoretical concept and operation of the proposed converter are justified through simulation results.
