Abstract
A power system (150) operable to implement a power balancing control scheme is provided. In one aspect, a power system (150) includes multiple independent power supplies (182A, 182B) with independent batteries (172A, 172B) feeding onto a common power bus (180). The power supplies (182A, 182B) regulate the voltage on the common power bus (180) at the same time. The power balancing control scheme, when implemented, causes the load on the common power bus (180) to be shared among the individual power supplies (182A, 182B) with a specified load distribution. The specified load distribution can be set or determined to balance the State of Charge (SoC) of the batteries (172A, 172B) over time whilst taking into account the constraints or limits of the elements (172A, 172B, 182A, 182B) of the power system (150).
