The rising cost of conventional energy sources and their environmental impact requires the implementation of renewable energies such the photovoltaic energy, which had increased exponentially in the last years. Thus, it is important to develop emulators that allow the testing and improving these systems. The motivation corresponds to the need for a simulator able to test PV inverters and their MPPT algorithms in conditions near to real-time. During the work to prepare the dissertation, various topics regarding the photovoltaic panel, LabVIEW programming and programmable power supply were...
