2-Phase Interleaved Boost Converter for Renewable Energy Source with Nonlinear Control

Article Preview

Abstract:

This paper presents a two-phase interleaved boost converter with nonlinear control for solar cell applications. The advantage of the interleaved technique is the reduction of the ripple current drawn from the energy sources. Traditionally, to control a DC-DC converter, a linear multiple-loop feedback control technique is often used. In this paper, we propose a nonlinear control technique which is based on Flatness system properties for the voltage loop and a nonlinear control based on sliding-mode for the current loop. The main feature of the used controller is that it can control the converter at any operating point. The validation of the proposed system is demonstrated through experimental results.
