Resumo
This paper presents a two-stage photovoltaic system based on a three-phase induction machine for water pumping purposes. The system is designed to work in isolated mode as it is intended to use in remote areas. A control algorithm is proposed for a DC-link voltage regulation and boost current control in a cascaded loop. The induction machine has a speed control based on V/F scalar method. Experimental results demonstrate the behavior of the systems for different levels of irradiance, temperature and load.
