Universal PV regulator based on low cost microcontroller

DC microgrids are becoming an economical alternative for local power generation. The mix of different renewable energies makes it necessary to use electronic systems compatible between them to supply common loads. This paper presents a photovoltaic regulator that can operate in the MPP of PV arrays regardless of the input PV array configuration or the output voltage required. Parallel connection thanks to its current-source behavior is also proposed. This allows the plug-and-play installation of the device without the need to get rid of previous equipment.
