A new controller for maximum power Extraction from photovoltaic system using Phase Modulated Converter.

The paper presents controller design for phase modulated full bridge topology based boost converter for Photovoltaic (PV) applications. Extraction of maximum power from PV panel is ensured by Phase Modulated Converter (PMC) while the controller used, utilizes Incremental Conductance (IC) techniques for computing operating Maximum Power Point (MPP) in a very simple and effective manner. Subsequently, MATLAB/Simulink model of PV panel, converter and control scheme are presented. Simulation results are analyzed in order to validate the performance of proposed controller under varying environmental conditions. Results derived shows efficient tracking of MPP by the designed controller under robust operation. [ABSTRACT FROM PUBLISHER]
