Development of an efficient photovoltaic MPPT Controller

摘要

A Maximum Power Point Tracking (MPPT) Controller using a buck converter has been designed and developed for a standalone Photovoltaic(PV) array. Perturb and Observe (P&O) algorithm has been implemented on a microcontroller to achieve the maximum power output from PV array. The whole developed hardware system has been tested with and without MPPT in a conventional PV array. The results show that the introduction of MPPT controller increases the efficiency of the conventional PV array.
