Comparison of Interleaved Boost Converter Configurations for Solar Photovoltaic System Interface

Abstract

Solar photovoltaic (SPV) panels that convert light energy into electrical energy through the photovoltaic effect have nonlinear internal resistance. Hence, with the variation in the intensity of light falling on the panel, the internal resistance varies. For effective utilization of the SPV panel, it is necessary to extract the maximum power from it. For maximum power extraction from SPV panels, DC-DC converter interface is used. The problem in using high frequency converter interface is the resultant high frequency ripple interaction with the SPV system. In this work, an interleaved boost converter (IBC) is considered to reduce the ripple. Our finding is that IBC fed by a SPV panel reduces this ripple to a greater extent. IBC also has a faster transient response as compared to conventional boost converters with reduced ripple contents. The main aim of this paper is to present a comparative analysis of the performance of IBC with inductors that are coupled in different ways. The results of the simulation were extrapolated with the help of MATLAB software and verified through experimentation.

PV System based Zeta Converter with Three-Phase Inverter For High-Speed BLDC Motor Applications

“…The magnetic field, flux distribution and current density of the core also increased in performance [4]. The interleaved boost converter coupled directly with the inductors have drastically reduced the ripple [5]. The use of 3 phase switching with TAF to reduce switching number in sampling period and commutation torque ripple [6].…”

Interleaved boost converter for global maximum power extraction from the photovoltaic system under partial shading

“…Whereas, both series-connected and parallel-connected MIC are adequate to PS and can track the GMP of each module hence the GMP from the whole PSPV system is extracted but they make the PV system more sophisticated and the cost of total installation is high [19,[26][27][28]. Finally, enormous researches [29][30][31][32][33][34][35][36] proved that an interleaved DC-DC boost converter might achieve many benefits compared to the single boost converter in terms of DC-link voltage regulation, ripples reduction, power savings, reliability and overall efficiency. In addition, reduction of the semiconductor switches rating will participate mainly in cost saving and thermal stress reduction on the switches.…”

“…In addition, reduction of the semiconductor switches rating will participate mainly in cost saving and thermal stress reduction on the switches. Some researches [29,32,33] applied the interleaved boost converter (IBC) with the PV system under uniform radiations only. Based on the previous literature, this study is considered as the first study to determine the best PV system configuration not only to mitigate and deal with PS but also to extract the GMP available based on the technical and economic assessment.…”

Maximum Power Extraction from a Partially Shaded PV System Using an Interleaved Boost Converter

“…Recently, many literature studies [45][46][47][48][49][50][51][52][53][54][55] have been done to prove the superiority of the interleaved DC-DC converters compared to the CBC with constant input power in terms of ripples, energy savings, efficiency, steady state, electromagnetic emission, and reliability. For example, the researchers in [47,50,52] have shown the possibility of using IBC with PV in terms of reliability evaluation, ripple reduction and faster transient response. However, they performed their studies on standalone PV without PS in order to highlight the IBC performance where the input power is constant, which is different under PSCs.…”
