Variable Frequency Control of MPTT using Two-Stage Grid Converters -Integrated Photovoltaic System

In this paper, a cascade control technique implied for a three-phase grid-tied photovoltaic system, has been proposed. This last comprises of a PV generator, a DC/DC converter, an inverter and an electrical grid. In this structure, a new control strategy using the simplified sliding mode technique is developed for the inverter. While the boost converter control strategy has two objectives, namely,...
