    摘要： Voltage conversion and charging circuitry and method for converting an alternating current (AC) voltage to a direct current (DC) voltage for charging an energy storage element (e.g., battery or supercapacitor). An output capacitance, which is initially charged quickly for use in the slower charging of a battery, also maintains the charge on an input capacitance which provides power for the charging control circuitry during such charging process. In accordance with a preferred embodiment, the DC charging current is substantially constant during a first time interval following which the DC charging power is substantially constant during a second time interval.

    摘要： A system includes multiple power modules, each having multiple power cells coupled in series. Each power module has a charge that is based on charges of the power cells in that power module. The system also includes multiple active cell balancing circuits, each configured to substantially balance the charges of the power cells in an associated one of the power modules. The system further includes an active module balancing system configured to substantially balance the charges of the power modules by charging a first subset of the power modules and/or discharging a second subset of the power modules. The active module balancing system could include multiple module balancing circuits, each associated with one of the power modules and configured to charge or discharge its associated power module. A direct current (DC) bus can be configured to transport DC power between the module balancing circuits.
