Abstract

This paper proposes the modeling e control of a flyback interleaved converter in order to use the energy provided for a photovoltaic module. The proposed modeling and controller aim to regulate the output voltage at 400 V. A parametric identification is applied to estimate the parameters of the converter, using the least squares method. In order to achieve the regulation of the output voltage, an RST digital controller is designed. Simulation results are shown to demonstrate the effectiveness of the modeling and controller proposed for the high step-up DC-DC flyback interleaved converter.
