Design and Implementation of Perturb and Observe (P&O) MPPT Technique for Negative Output Super-Lift Luo Converter

Abstract:

TThe growing energy demand in recent years has led to increased use of renewable energy resources. Among all renewable energy sources, the photovoltaic (PV) power generation acts as a green source which is free from greenhouse emissions to provide feasible solution to the increasing energy demand. However the non-linear nature of the solar module, their low-efficiency and high capital cost is being the major hindrance to the penetration and reach of the solar photovoltaic systems. To overcome this non-linearity, this paper presents the implementation of Negative Output Super-Lift Luo converter (NOSLC) with the solar panel. NOSLC is a type of super-lift converter in which the negative output voltage increases in geometric progression. Along with this, to track the maximum power from the PV cell, a technique named Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) is employed. This proposed system is modelled and simulated using MATLAB/Simulink and validated with the theoretical calculations.
