This work presents a new maximum power point tracker system for photovoltaic applications. The developed system is an analog version of the "P&O-oriented" algorithm. It maintains its main advantages: simplicity, reliability and easy practical implementation, and avoids its main disadvantages: inaccurateness and relatively slow response. Additionally, the developed system call be implemented in a practical way at a low cost, which means an added value. The system also shows all excellent behavior for very fast variables in incident radiation levels. (C) 2009 Elsevier Ltd. All rights reserved.
