Abstract: A wireless power transfer system is disclosed. The wireless power transfer system includes a first converting unit configured to convert a first DC voltage of an input power to a first AC voltage. Further, the wireless power transfer system includes a contactless power transfer unit configured to receive the input power having the first AC voltage from the first converting unit and transmit the input power. Also, the wireless power transfer system includes a second converting unit configured to receive the input power from the contactless power transfer unit and convert the first AC voltage of the input power to a second DC voltage. Furthermore, the wireless power transfer system includes a switching unit configured to regulate the second DC voltage across the electric load if the second DC voltage across the electric load is greater than a voltage reference value.

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