Performance Evaluation of Boost DC-DC Converter for Different Loads to Extract Maximum Power from Solar PV Module

This paper presents a comparative performance analysis of the boost dc-dc converter in order to extract maximum power from a solar PV module for different load types. The three different types of loads considered are constant resistive load, constant voltage load and constant current load. The condition on duty ratio of the boost converter has been obtained to extract the maximum power from the solar PV panel for different loads. The analysis has been done for all the three types of the loads and different behaviour of the boost converter has been observed. It has been shown that the I-V characteristics is sensitive near the MPP, on the right side of the MPP and on the left side of the MPP, respectively for the constant resistive, constant voltage and constant current loads. Simulation has been performed on MATLAB/SIMULINK software to verify the comparative performance. Experiments are done with three practical load of resistive heating, battery charging, and fan load, which corresponds respectively to constant resistive, constant voltage and constant current loads, and verifies the results.
