If controller 518 decides, in the preliminary decision, to override a voltage-change decision by controller 516, it may then make a voltage-change decision. That voltage change decision may be to switch a converter (or more than one converter) to pulse or to not pulse.

In some embodiments, these two decisions may be compacted into one. For example, controller 518 may decide, at the beginning of each cycle, between three options: to switch a converter (or more than one converter) to the “on” state (i.e., pulsing), to switch a converter (or more than one converter) to the “off” state (i.e., not pulsing), or to defer to the current or most recent voltage-change decision by controller 516. In other embodiments, power controller 516 and 518 may be in communication, and may determine together which of power controllers 516 and 518 should be active at any given time.

In some embodiments, power controller 518 may not be included as a physical component in the system. Rather, the actions of power controller 518 may be performed by an algorithm, or a series of algorithms, as part of power controller 516. In these embodiments, these algorithms or series of algorithms may take the form of a series of logic gates within or connected to controller 516 that determine whether to control power according to a steady-state pattern or an oversampling pattern (e.g., with “controller” 518). For example, controller 516 may contain two decision-algorithms: a steady-state algorithm and an oversampling algorithm. Each algorithm may make a voltage-control decision at the beginning of each steady-state cycle, and the oversampling algorithm may also make a voltage-control decision at the beginning of each oversampling cycle.
