2. PROJECT OVERVIEW Photovoltaic (PV) generation offers advantages like no fuel costs, low maintenance, and no pollution. However, PV modules have low efficiency, necessitating a high-efficiency power conditioning system (PCS). A single-phase PV PCS consists of DC-DC and DC-AC conversion stages. The DC-DC converter controls maximum power point tracking (MPPT) via duty ratio modulation. Though commonly used, the Cuckoo algorithm has limitations. A cascaded converter improves efficiency for high-power applications, reducing conduction loss and voltage ripple. The proposed topology predicts the optimal duty ratio based on solar irradiation.
