In a cascade multilevel converter, the difference in power cell illumination causes the duty cycle to vary between these cells while maintaining Maximum Power Point Tracking (MPPT). However, the cell duty cycle difference is undesirable because it is corresponding to the result voltage and current mutilation. In such manner, staggered geographies for photovoltaic (PV) applications using H6 bridge power cells instead of H-bridge cells are proposed. If there is a solar mismatch between the power cells, the proposed converter will power the shaded cells at a lower voltage without changing the voltage of the solar module. So it continues to run MPPT. This modification ensures that all power cells maintain the same cycle of work in any weather conditions. Therefore, it maintains excellent Output voltage and current characteristics. To test the viability of the proposed arrangement, detailed simulation models and test prototypes were constructed. They got results show that the proposed geography gives fundamentally worked on output voltage and current characteristics compared to the cascaded H-bridge. The performance of the proposed topologies is also compared with the topology providing improved harmonic performance according to European efficiency, with a recorded improvement of 2.64%.
