Abstract :
In this paper, a new MPPT system has been developed, consisting of a buck-type dc/dc converter, which is controlled by a micro-controller-based unit. Based on the nonlinear characteristics of photovoltaic (PV), these paper designs a VSS controller to realize the maximum power output of PV arrays and introduces the system fundamental. Comparing with other techniques used in the past, the use of the proposed MPPT control improves the PV system performance. And the results of simulation and experiment are present.
