Development and comparative evaluation of power management systems for advanced photovoltaic architectures

This paper introduces a full comparative evaluation of the advanced PV architectures especially for energy harvest application. The comparative evaluation involves module architecture, sub-module architecture, and cell architecture. The comparison includes the capability of theses PV architectures to mitigate the effect of the mismatch loss that inherently comes from different irradiation on the PV system. Then, the effect of the bypass diodes on the PV performance under these three architectures is also considered. A case study is demonstrated to validate the different features of the mentioned PV architectures using PV module consists of 24 PV cells. Finally, simulation and experimental results for PV cell architectures using buck-boost converter is presented to investigate the features of the PV cell architecture and its challenges in the future.
