Solar energy is an excellent source of renewable energy, despite its intermittent nature that can pose a challenge. To meet load demand, converter required to integrate the system. The acts based on control signals from controller, which trained according end demand and availability Sun Irradiance. This paper utilizes Incremental Conductance (IC) Perturb Observe (P&O) algorithms, are widely accepted in industry easy implement. study aims design compare Step Voltage (SV) controller Step-Duty (SD) Maximum Point Tracking (MPPT) IC controller-based DC boost converter. compares performance SV SD converters under different environmental conditions, evaluates system's effectiveness by comparing oscillations power for both conditions discusses impact battery charging Load. system tested using MATLAB Simulink/coding, considering Indian solar radiation intensity (SRI) scenario temperature variations. Overall, this provides comprehensive analysis proposed system, contribute development optimization systems various applications. From comparative SD, P&O it observed superior. MPPT point also discussed.
