Boost derived hybrid converter for interfacing renewable energy sources with microgrid

This paper addresses the emerging need for efficient electric power utilization by focusing on microgrid development. The integration of renewable energy sources in power systems through nano grid and microgrid architectures has gained momentum. Accommodating diverse load types, including DC and AC loads, necessitates advanced power electronics converters and controllers. The prevailing practice of employing separate DC-DC and DC-AC converters for solar-photovoltaic systems is cost-intensive due to dual converter requirements and supplementary compensators. To overcome this, a novel Boost Derived Hybrid Converter (BDHC) topology is introduced, capable of powering simultaneous DC and AC loads using a single DC input. Achieved through a boost converter enhancement, this innovative configuration replaces a single switch with four voltage source inverter (VSI) switches. This advancement streamlines power provisioning to both AC and DC loads, presenting a promising solution for microgrid and nano grid applications in residential environments. Extensive simulations using MATLAB and Simulink are performed to validate the proposed circuit. The also paper presents the grid integration results of the hybrid converter, demonstrating its ability to achieve a close-to-unity power factor at the grid input.
