A method for controlling peak and valley of a controlled current in a switched mode power supply comprising a current mode control loop and being connected to an electrical power source. The method comprises providing an upper compensation ramp signal for controlling a peak of the controlled current, the upper compensation ramp signal being a sawtooth signal with a negative, falling, substantially linear slope (−S.sub.e,Upper), starting periodically in time. The method further comprising providing a lower compensation ramp signal for controlling a valley of the controlled current, the lower compensation ramp signal being a sawtooth signal with a positive, raising, substantially linear slope (S.sub.e,Lower), starting periodically in time. The method additionally comprising providing a reference voltage signal (V.sub.ref), to the control loop, and obtaining a signal indicative of the controlled current (I). Finally, the method comprises comparing alternatingly the signal indicative of the controlled current referenced to the reference voltage signal to the lower compensation ramp and the upper compensation ramp, respectively, to switch on or off the electrical power from the electrical power source into the control loop, and switching the electrical power with modulation at a fixed frequency (f.sub.s).

A first direct-current to direct-current (DC-to-DC) converter is configured to convert an input direct-current voltage to an output direct-current voltage with a regulated charging current consistent with a target charging current limit or range established by the current estimator for the charging mode and respective cell identifier(s) determined by a cell balancing module for the charging mode for the time interval. A first controller is capable of controlling the charging, individually or collectively, of each of the battery cells by adjusting/controlling the regulated charging current outputted by the first DC-DC converter and/or the duty cycle of switches of the first DC-to-DC converter based on the target charging current limit or range for the time interval.

The target device may include an adapter connection switch that receives adapter recognition information to form a connection with the adapter, a voltage detection unit that receives an output voltage from an adapter, and a voltage-change-requesting unit that outputs a voltage to request a voltage change based on information on the output voltage from the adapter. The adapter may include a device information recognition unit that receives the voltage to request a voltage change, and an output-voltage-changing unit that changes the output voltage based on the voltage to request a voltage change.

A power supply system includes a plurality of power supplies coupled to a common power bus. Each of the plurality of power supplies adjusts an output voltage set-point within a droop window in response to an excursion sensed voltage on the common power bus reflecting the current load on the power supply system. In response to a transient in the sensed voltage being above or below the droop window, each power supply may shift its droop window up or down. If the droop window of each power supply is at a maximum or minimum value within a voltage regulation window, each power supply may respond to a transient in the sensed voltage by compressing the droop window.
