Performance Analysis of Non-Isolated Bidirectional DC-DC Converters for Renewable Energy Application

Abstract

This research looks at four distinct topologies for non-isolated bidirectional DC-DC converters, all of which are reshaped to renewable energy generation systems. This study focuses on four different types of DC-DC converters: NHIBC, NCBBBC, NBIBZSC, and NBIB. Variations in temperature and precipitation can cause immense swings in the input voltage of renewable power systems like wind and photovoltaic (PV) panels. Taken together, these obstacles have historically limited the total amount of electricity generated by renewable sources internationally. An ideal candidate for DC microgrid integration would be a non-isolated DC-DC converter, which excels in low-voltage applications. The NHIBC architecture manoeuvres all of these and more, making it more efficient even when input conditions aren't predictable. The converters are tested using a variety of important performance measures, including efficiency, voltage and current ripple, component size, and circuit intricacy. Simulation results ran in MATLAB 2023a demonstrate that the NHIBC has the most balanced performance, making it the optimum alternative for modern renewable energy applications.
