Abstract
This paper presents the analysis, design and simulation results of a dc-dc LLC resonant converter fed by photovoltaic (PV) panels. In order to achieve MPPT (Maximum Power Point Tracking), a Variable Inductor is used to control the converter operation. In order to analyze the converter operation a simple dc load (resistor with fixed value) is considered and simulations results are presented considering different irradiance conditions of the PV panels. The system specifications are presented and simulation results were obtained considering different irradiance conditions.
