Abstract: Techniques related to a power module employing multiple power sub-modules are described. More specifically, an embodiment combines and controls multiple power sub-modules of varying characteristics to improve the overall efficiency of the power module across varying load currents, power outputs, input voltages, and other operating conditions. Moreover, the power module may employ an adaptive non-linear and non-uniform current/power sharing among its power sub-modules. Other embodiments are described and claimed.

Abstract: Some embodiments of the invention may operate to measure a feedback error signal change as an indication of efficiency associated with a power stage, and to select a determined power stage parameter value to increase the efficiency responsive to the feedback error signal change.

Abstract: In some embodiments, a switching mode power converter has an input and an output. The switching mode power converter may be configured to transition between a continuous conduction mode at a first load level and a discontinuous conduction mode at a second load level, where the second load level is lower than the first load level. A control circuit may be connected to the switching mode power converter, wherein the control circuit is configured to adjust the switching frequency of the switching mode power converter during the transition between the continuous conduction mode and the discontinuous conduction mode in accordance with maintaining low voltage deviation with respect to a reference voltage. Other embodiments are disclosed and claimed.

Abstract: A power converter uses a control method to optimize efficiency by dynamically optimizing a controlled parameter. A change in efficiency of the converter after changing at least one controlled parameter is determined. The direction of change in efficiency of the converter is compared to a direction of the change in the controlled parameter. The controlled parameter is changed in a positive direction when the direction in the change in the efficiency of the converter and the direction of the change in the controlled parameter are the same and changed in a negative direction when the direction in the change in the efficiency of the converter and the direction of the change in the controlled parameter are opposite. The controlled parameters may include dead time between turn-on and turn-off and between turn-off and turn-on of the primary and corresponding secondary side switches of the controller, drive voltage(s) for the switches, and intermediate bus voltages.
