Abstract

Photovoltaics (PV) module is created by connecting the numberof PV cells in series and parallel, depending on the voltage and current rating respectively. Due to partial shading, mismatching or failure of a single PV cellcancreate many anomalies in the proper functioning of a PV module. If ignored then it can reduce theoverall efficiency of an affectedPV module. In comparison to the typical series-parallel, other topologies like Total Cross-Tied (TCT), Bridge Link (BL) and Honey-Comb (H-C) in PV performed much better in reducing the effect of partial shading.Recently, PV modules embedded with CMOS switches have shown better capability in dealing with partial shading by being able to reconfigure between different configurations (number of PV cells connected in series versus parallel) in real time. Moreover, the CMOS embedded PV module can create a power island that is ideal for matching the generated power with the load for an optimal power transfer.The performance of a PV module embedded with CMOS switches in comparison with various other topologies (TCT, BL, and H-C) of PV modules under various shading pattern is presented in this presentation. For all the topologies the maximum power generated is compared by keeping the same number of PV cells and shading pattern. The I-V characteristics for each case is generated by using Matlab and Spice simulation. In this study, the PV module embedded with CMOS switches outperformed in mitigating the effects of partial shading using reconfigurability compared to fixed PV module topologies (TCT, BL, and H-C).
