Design and Simulation of an MPPT Charge Controller for a PV Application

Abstract

Abstract. In this document, we propose an MPPT charge controller based on the two-phase charging method proposed by the datasheet of the battery under test. Also, for efficient and optimal charge the charge controller reacts with better exploitation of the available photovoltaic (PV) power by means of a maximum power point tracking (MPPT) technique employed in the control algorithm especially the Perturb and observe (P&O) techniques; when threshold voltage reach, the regulation phase start. The MPPT and converter efficiency are respectively 98.7% and 98.2% at the standard test condition (STC).
