Tracking the Maximum power point (MPP) in Photovoltaic (PV) systems need current and voltage sensors to measure the SCA (Solar Cell Array) Ampere and voltage continuously. At the same time, using a lot of sensors makes the system more expensive and more complex. This paper applies a current sensor less technique that uses voltage sensor only without need for current measurements depending on a novel Fourth Order Buck Converter (FOBC) which replaced conventional buck converter in recent researches. The objective of this paper is to study the behavior of FOBC in addition to analyzing the performance of the proposed MPPT technique. The whole system is studied and simulated depending on the MATLAB environment to achieve this purpose.
