The simulated system consists of the BP SX 150S photovoltaic (PV) module, the ideal Cuk converter, the MPPT control, and the resistive load (6?). The selection of the purturb & observe (P&O) algorithm permits the use of output sensing control method which eliminates the input voltage and current sensors. The direct control method adjusts of duty cycle within the MPP tracking algorithm. The way to adjust the duty cycle is totally based on the theory of load matching. When the value of Rload matches with that of Ropt, the maximum power transfer from PV to the load will occur. These two are, however, independent and rarely matches in practice. The goal of the MPPT is to match the impedance of load to the optimal impedance of PV. November 2012 - January 2013 Copyright © 2013 i-manager publications.
