Dual switch High Gain Boost Converter for DC microgrid Applications

DC microgrids are becoming more reliable by integrating renewable power generators like fuel cells and solar PV systems. Connecting these DC power generators to the direct current (DC) microgrid requires high voltage gain DC-DC converters due to their low voltage limit on the output side. This work proposes a new high gain converter with two switches for DC microgrid applications. Convectional DC-DC converters typically only have one inductor and one capacitor, which results in a low voltage gain because only one inductor charges the capacitor. The suggested converter uses a set of two inductors and two capacitors for a high-voltage gain. In the proposed converter, two inductors are connected in shunt or series for the charging and discharging modes. In this paper, an in-depth examination is provided of the proposed converter’s steady-state analysis for 380V DC micro grid. The MATLAB 2022a Simulink version used to test the proposed system’s functionality.
