Parabolic interpolation based maximum power
point tracking (MPPT) technique has been used in this paper to
track the maximum power point (MPP) of a photovoltaic
system. The proposed technique requires only one current
sensor to track the MPP, which means that systems
incorporating this technique will need less hardware support
and will be cost effective. The proposed technique has been
applied on the simulation and experimental data of a charge
controller circuit and it has been found that the proposed
technique requires around 50% less iteration to track the MPP
than the tradition P&O method.
