This converter is suitable for photovoltaic (PV) systems with modest input voltages due to its high efficiency, decreased voltage stress, and high step-up voltage gain. Although the multilayer structure enables a greater voltage gain, the interleaved configuration minimizes current ripple and modest Although the multilevel structure enables a greater voltage gain, the interleaved configuration minimizes current ripple and improves efficiency. PV fed the maximum output voltage is 255 V for the third level. MATLAB/Simulink is used for a comprehensive analysis and simulation of the IMCBC, demonstrating its effectiveness in converting DC power from a PV-fed h-bridge inverter into AC power.
