A Reconfiguration Circuit to Boost the Output Power of a Partially Shaded PV String

An optical isolator circuit is developed to detect and dynamically relocate the photovoltaic (PV) module under partial shading. The suggested system control structure operates in two modes. Mode 1 governs at global maxima (GM) by tracing power-voltage curve. 2 detects separates all bypassed modules from a PV string/array means of decentralized stores its power battery. Simulations are performed on different shading patterns verify efficacy system. results showcase that averaged harnessed using proposed 25.26% more than total cross-tied (TCT) series-parallel (SP) array configurations. does not require complex gate driver circuits large switch counts. scalable can be implemented an “N × N” array.
