A Ladder Architecture for Power Improvement and Multi-Peaks Elimination in PV Arrays during Non-Uniform Irradiance Scenarios

Solar Photovoltaic (PV) arrays are vulnerable to non-uniform irradiances that diminish their power generation and introduce complexities by creating multiple peaks in the power-voltage curves, ultimately leading to reduction in overall performance. Various mitigation techniques are proposed in the l...
