Variable frequency controlled incremental conductance derived MPPT photovoltaic stand-along DC bus system

An incremental conductance (IC) derived MPPT PV stand-along dc bus system by constant-duty variable frequency control is proposed. Fast matching process to executing MPPT PV system is achieved by a simple control programming. The proposed PV system can provide enough energy to load as well as the battery charging with the residual energy. The feasibility is demonstrated by an example of 220 W PV stand-along dc bus system with IC MPPT control. The MPPT tracking phenomenon for energy drawing from PV array and supply to load is quite close to the prediction.
