Improvement Performance of Standalone PV System Based on a New Quadratic Boost Converter

Abstract

Numerous studies are being conducted to design more effective photovoltaic (PV) systems that use DC/DC converters. The design of a new quadratic boost for use in PV applications is discussed in this study. The design is based on an incremental conductance (INC) in the maximum power point tracking (MPPT) method. An improved architecture is used in this type of boost, and it can deliver a high conversion voltage ratio despite having low duty cycle values. The suggested topology is controlled by a hard switching signal derived from PWM and has a variable duty cycle based on the MPPT algorithm. The practical verification has been completed, and the INC algorithm has been programmed onto Arduino Nano. The quadratic boost converter (QBC) is verified in real-time using an actual PV module. The simulation and experiments' results validated the proposed topology's practicality for use in PV applications.
