Abstract

The power supplied by photovoltaic panel is sensitive to radiation incident on itself. Both isolated and grid connected applications are very important output voltage. The load usually works in constant voltage. Variation on radiation levels may lead to no voltage. This work presents the use of a PID controller in a converter able to provide constant voltage for an isolated system even during radiation variation in solar panel. presents a PI controller to a three-phase inverter connected system. The controller is designed power produced by the photovoltaic panels on the grid.
