Abstract
In this paper, the effectiveness of these three different control algorithms is thoroughly investigated via simulation
and a proposed efficiency evaluation method of experimentation. Both the steady-state and transient characteristics of
each control algorithms along with its measured efficiency are analyzed. Finally, a novel two-mode maximum power
point tracking (MPPT) control bining the modified constant voltage control and ond method is
proposed to improve the efficiency of the 3 kW PV power generation system at different insolation conditions. Finally, a
novel two-mode MPPT control bining the modified constant voltage control and ond method is
proposed to imp
