Solar PV Integrated MPPT Controlled High Gain DC-DC Converter

Abstract

—This paper presents the integration of solar panels into standalone applications using a high-gain DC-DC converter coupled with an MPPT (Maximum Power Point Tracking) con troller. Specifically, a Non-isolated Interleaved Quadratic Boost Converter topology serves as the DC-DC converter for the charge controller implementation. The Perturb and Observe method is the MPPT algorithm used, and it tracks the solar panel’s maximum power. An interleaved quadratic boost converter raises the voltage while the photovoltaic array collects solar radiation and produces electricity. The performance of a high-gain con verter, designed with specifications for 600W, 16/400V, and a 40KHz switching frequency, is validated through simulation using MATLAB SIMULINK, achieving an efficiency of 94.53%.
