These findings indicate that the proposed converter is a promising one to be used in microgrids because of its high voltage gain, high efficiency, and reduced voltage stress across the switches. In Fig. 14, the efficiency versus duty ratio curve is illustrated.
Illustrated in Fig. 1, a DC microgrid relies on high-gain DC–DC circuits to bridge between loads and sources, elevating low voltages (12–60 V) from batteries, solar PV, and fuel cells to higher DC voltages (200–300 V). Additionally, these converters regulate the DC-link voltage to the desired level.
In modern DC microgrids, a blend of supercapacitors and high-gain converters is used due to the supercapacitors' high power density despite their low voltage rating. Additionally, high-gain converters are crucial for level three fast charging of electric vehicles.
Research should explore integrating storage solutions to enhance the system's resilience and cost-effectiveness. DC microgrid systems can achieve much broader functions and could be applied to many areas due to developments in power electronics (converters), real-time controllers, and renewable energy resources.
