Design and Optimization of a Maximum Power Point Tracking controller for a PV battery charger

In this paper the design criteria for a Maximun Power Point Tracking (MPPT) controller of a dc-dc converter for photovoltaic (PV) applications are presented. The switching converter matches a single panel with a battery and performs the maximum power point tracking at the battery's terminals instead that at the panel's output. Comparisons among analytic results, simulations and experimental measurements on a laboratory prototype are presented and discussed.
