Abstract: Embodiments herein provide a system and method for controlling extraction of power from multiple Photo Voltaic (PV) arrays. At least two converters and at least two Photo Voltaic (PV) arrays are configured. The power extraction is controlled through one of an injection of Direct Current (Idc) into output current of each of the at least two converters, or by performing a phase shifting of each of the output current of each of the at least two converters.
