The aim of all new converter topology for a photovoltaic system is the improvement of efficiency.
Although the maximal efficiency of a converter must be taken in consideration, when it comes to
evaluate a photovoltaic conversion chain, the most significant of the efficiency definitions are the global
or the total efficiency and the European efficiency.
The global efficiency takes into account all the structures presented within the photovoltaic conversion
chain, that is, the power converter and its associated MPPT control. It is defined by the multiplication of
efficiencies of both structures or in other words, by the relation between the converter output power and
the maximal power available in the PV [5].
