Abstract: The solar panels require Maximum Power Point Tracking (MPPT) methods to operate at the unique operating point called as Maximum Power Point (MPP) in spite of changing environmental conditions. For a given solar irradiation and temperature the maximum power that a panel can deliver is extracted by the use of power converter whose duty cycle is adjusted based on the MPPT method. In this study, revised form of variable step size Incremental Conductance (INC) method that adjusts the step size considering the PV panel current is introduced. Also, the method has all the merits of conventional INC method. The simulation is carried out in MATLAB/SIMULINK environment and results of conventional, variable step size and revised variable step size Incremental Conductance methods are compared. The simulation works confirms that the proposed method is better in terms of its convergence speed and accuracy. Moreover, the suggested method is well suitable for practical operating conditions due its wide operation range.
