Abstract: Over the past two decades, multi-level inversion (MLI) techniques have become increasingly suitable for high-power industrial applications. Multi-level inversion (MLI) integrates multiple DC sources. For this reason, it is advised to use switches with higher nominal values. All topologies are accurately simulated, and the results are verified and compared. The duty cycle of individual cells in the multi-level converter cascade varies depending on the change in the illumination power of the cells. However, MPPT is maintained throughout the process. On the other hand, the difference is the role of cell cycle suppression, as it pertains to development and current reduction. To achieve this goal, multi-cell photovoltaic (PV) applications have been proposed, where H6 power bridge cells replace H-bridges. In the absence of solar radiation mismatch among the power cells, the proposed converter can provide energy from the shaded cells at a lower voltage without altering the PV voltage, thus maintaining the MPPT feature. This adjustment allows for the same duty cycle to be maintained across all power cells, regardless of weather conditions, and therefore preserves the output voltage and current fluctuation characteristics of the power cells. To assess the performance of the proposed device, both a complex computer model and a field experiment have been utilized. After analysis, it was shown that the proposed topology offers significantly better voltage and current characteristics in a production environment compared to the conventional H-bridge topology. The proposed topology was compared with a topology that improved harmonic representation consistent with European educational standards, resulting in a 2. 64 percent improvement in overall performance quality.
