Abstract
An interleaved power converter is constructed so as to substantially equalize the power output of individual converter slices or phases. In an embodiment of the invention an interleaved power control system (110) includes a power bus (114) having a battery (116) coupled thereto and a plurality of slices (112) operating in a phased relationship with one another for causing the battery to source current to the power bus or to sink current from the power bus. Each of the slices includes an inductor (L) that is switchably coupled to the power bus and a controller (146) for controlling the switching of the inductor. The switching of the inductor is controlled as a function of (a) a difference between a magnitude of a voltage potential (V.sub.B) of the power bus and a predetermined voltage potential magnitude (Voltage Setpoint); (b) a difference between a magnitude of a current flowing through the power bus (I.sub.T) and a predetermined current magnitude (Charge Current Setpoint); and (c) a signal that indicates both of (i) a predetermined proportion of a total amount of current that the power converter system is supplying and, (ii) a magnitude of a peak current flowing through the induc…
