Practical Implementation of an Embedded Controlled High Gain Interleaved Boost Converter for Solar Installation System

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.
