Abstract: The power processing is an important aspect of a spacecraft power systems. This involves circuitries for carrying out the functionalities of array control, battery charging and bus regulation. Conventionally these functions are carried out by standalone sub functional units. These functional units are available in different panache. A power system configuration is thus a combination of a set of matching functional entities together carrying out the power control and management. Though distinct power system configurations are tailor made for specific mission scenario, they fell short of optimality required for small satellite missions. Hence a scheme comprehensively addressing such requirements has been a necessity. In this regard, an integrated array controller and battery charger leveraging the limitations of the present schemes is simulated using Matlab and an hardware amounting to this design has been developed.
