Impact of P&O and Incremental Conductance MPPT Algorithms on DC-Link Voltage Ripple in Photovoltaic Boost Converter Systems

Year: 2026

Type: conference-paper

Abstract: Photovoltaic (PV) systems interfaced with DC-DC converters rely on maximum power point tracking (MPPT) for efficient energy extraction and stable DC-link performance. Although MPPT methods are commonly assessed in terms of tracking efficiency, their impact on DC-link voltage ripple is less explored. This study compares Perturb and Observe (P&O) and Incremental Conductance (INC) MPPT techniques for a PV-fed boost converter using MATLAB/Simulink under variable irradiance conditions. Results show that P&O exhibits a DC-link voltage ripple of 21.48%, while INC reduces it to 19.72%, corresponding to an 8.2% reduction in ripple. Furthermore, the INC method provides a faster dynamic response and better steady-state voltage regulation. The MPPT efficiencies obtained are 96.67% for P&O and 99% for INC, demonstrating the superiority of INC in both power tracking and DC-link voltage quality.
