Abstract :
This paper presents the modeling and control design of an isolated full-bridge boost converter fed by a photovoltaic (PV) device. The converter and PV device are modeled using the method of average state variables and the controller is designed with the statespace feedback control technique, using concepts of characteristic polynomial, controllability and Ackerman´s matrix. The dynamic model of the converter is obtained and the voltage controller is designed in order to achieve the regulation of the input voltage of the boost converter, thus allowing the direct control of the PV voltage, which brings advantages when this system is compared to traditional control strategies for grid-tie PV converters. The modeling strategy and the controller design are carefully presented and simulation results obtained with Matlab/Simulink are presented.
