ENABLING VERY LARGE AND VERY SMALL DUTY CYCLES IN SWITCHING CONVERTERS

摘要

In accordance with embodiments of the present disclosure, an apparatus may include a switched-mode power supply and a controller. The switched-mode power supply may include an inductor and a plurality of switches coupled to the inductor. The controller may be configured to control an inductor current of the inductor by controlling the plurality of switches to operate the switched-mode power supply in at least three phases, the at least three phases comprising: a first phase having a first period in which the inductor current increases; and a second phase having a second period in which the inductor current decreases; wherein, at least one of the first period and the second period is defined by a difference in time between switching of at least two switches of the plurality of switches.
