Because of nonlinear characteristics of PV cell, the maximum power can be extract under particular voltage condition. Therefore, Maximum Power Point Tracking (MPPT) algorithms are used in PVA to maximize the output power. In this paper the MPPT algorithm is implemented using Ćuk converter. The dynamics of PVA is simulated at different solar irradiance and cell temperature. The PO MPPT technique is a direct control method enables ease to implement and less complexity. Keywords: Photovoltaic Array (PVA), MPPT, Ćuk Converter. 1. Introduction Among the renewable energy resources, the energy through the so
