Comparison of different control techniques for interleaved DC-DC converter

Abstract

Interleaved DC-DC converter with coupled inductor is used in standalone Photovoltaic, battery charger/discharger applications. The main issue of the Interleaved DC-DC converter is that, it does not provide constant output voltage for a change in input voltage. Therefore, the converter efficiency is reduced. Hence to overcome this drawback, proper controller has to be used. In this paper, different control techniques such as PI, PID and Fuzzy logic controller are used. The simulation was carried out using MATLAB/Simulink and the results were compared. Fuzzy logic controller provides better regulated output voltage with less settling time.
