Maximum power point tracking (MPPT) is one of the major issues in photovoltaic (PV) systems and plays a vital role inoptimal utilization of these systems for practical applications. In this paper, we propose a new MPPT method that requires onlyone current sensor in PV panel side and uses a fuzzy controller to generate proper duty cycle for the DC–DC converter in aPV system. The input current sensor-based fuzzy MPPT method (ICSF) exhibits proper operation both under steady state anddynamic tests and also performs well in case of severe environmental variations. The proposed method has been simulated inthe MATLAB/Simulink workspace and compared with some major MPPT methods. The results reveal that the proposed methodbehaves well in various conditions. © 2016 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
