TL;DR: A practical implementation of two stage interleaved boost converter for solar installation system is proposed and the performance of the converter is compared with the conventional boost converter and reveals that the present converter system has the advantages of high efficiency and reduced switching stress.
Abstract: In recent years, solar power generation has gathered much attention in the field of generation and research. The aim of this work is to develop a simulink model for closed loop controlled interleaved boost converter and test it. This paper proposes a practical implementation of two stage interleaved boost converter for solar installation system. The topology study of open loop and closed loop systems with step-up conversion and step increase in input voltage are proposed. The modified two-stage interleaved DC to DC boost converter is modeled and simulated using matlab/Simulink and it is implemented using embedded controller. The simulation and experimental results of this system are presented and compared. The performance of the converter is compared with the conventional boost converter. This comparison reveals that the present converter system has the advantages of high efficiency and reduced switching stress.

TL;DR: The modeling and Matlab simulink simulation of an interleaved and a cascaded DC to DC boost converters reveal that the cascaded boost converter system has the advantages like reduced number of switching component, low ripple content and high efficiency.
Abstract: The main objective of this work is to find the high efficiency DC to DC boost converter for solar power installation system. This paper mainly focuses the modeling of high gain with high efficiency DC to DC boost converter for photovoltaic system under wide input voltage range. The modeling and Matlab simulink simulation of an interleaved and a cascaded DC to DC boost converters are presented. An interleaved and a cascaded DC to DC boost converters are analyzed in open loop and closed loop condition. These converters provide the constant output voltage even the output voltage of the PV panel is continuously varying. The performance of these converters is compared. Based on the comparison result the cascaded boost converter is implemented using PIC microcontroller. This comparison reveals that the cascaded boost converter system has the advantages like reduced number of switching component, low ripple content and high efficiency.
