MPPT Based SPV System Design and Simulation Using Interleaved Boost Converter

Abstract

This article proposes an SPV system, based on maximum power extraction through interleaved boost (IB) converter. For this purpose the converter is connected between solar panel and load. The advantageous features of using interleaved boost converter are to provide highly increased voltage gain and faster transient response. It also reduces the ripple across output voltage, switching losses and electromagnetic interference. Interleaved Boost (IB) Converter with MPPT technology plays major role in terms of economic operation for power generation. In this paper the implementation of SPV system with IB Converter is analyzed with its operational characteristics using MPPT algorithm. The proposed system performance analysis is done by using P&O optimization method to achieve maximum power from SPV system. This proposed topology with IBC improves overall efficiency and minimizes the switching losses. The system performance is validated by simulation results using MATLAB software.
