摘要：
A method of randomizing inductor current in at least one of a plurality of parallel coupled peak/valley current-controlled power converters may include comparing the inductor current to a threshold to generate a comparison signal, delaying the comparison signal by a plurality of delay amounts to generate a plurality of delayed versions of the comparison signal, and randomly selecting one of the plurality of delayed versions of the comparison signal for controlling the inductor current during one or both of a charging state and a transfer state of the at least one of the plurality of parallel coupled peak/valley current-controlled power converters.
