Electronic Hybrid Power System for Charging a Lithium-Polymer Battery

This project implements a charger for lithium polymer batteries, using two different sources of energy: the grid and photovoltaic energy. The charge is switched so that, when the grid feeds the battery, the photovoltaic panel (PV) do not and similarly, when the PV feeds the battery, the grid does not. In this project, three algorithms for tracking the maximum power point (MPP) for a Photovoltaic Array are analyzed and simulated, and one of them is implemented. The power converters are modeled and simulated in order to analyze the general behavior of the system and to design the controllers that allow to regulate properly the involved variables.
