Abstract
Methods, systems, and devices are provided for optimizing a bus voltage supplied to a switching power converter to keep the duty cycle of the switching power converter to within a desirable operating range. In some embodiments, the duty cycle of the switching signal used to drive the switching power converter is monitored (e.g., indirectly) to determine whether the duty cycle is approaching an undesirable level. For example, as the duty cycle decreases (e.g., approaches or crosses a certain threshold), embodiments decrease the bus voltage. This may, in turn, allow the switching power converter to output substantially the same output to the load, while using a more efficient (e.g., larger) duty cycle. Certain embodiments use similar techniques, along with certain bus voltage optimization techniques, to control a bus voltage as a function of feedback from multiple switching power converters.
