Abstract
Photovoltaic (PV) energy has increased drastically at an average annual rate of 60% in the last few years. It quickly became an integral part of the power system networks. This increase, in turn, has triggered the evolution of PV power converters with more efficiency and reliability. In this paper, a prototype of the PV integrated controlled converter system is designed, which is applicable in water pumping for irrigation. Main components of this system are floating dual boost converter (FDBC), three-phase voltage source inverter (VSI) and three-phase squirrel cage induction motor (pump). For address the issue of PV voltage fluctuations, a voltage mode controller is designed for the FDBC which regulates the output voltage of the FDBC to a fixed value irrespective of any voltage fluctuations at the PV side.
