Abstract
A predictive controller for an inductive DC-DC converter comprising a switchable inductor is described. The predictive controller includes a DC-DC controller configured to generate a plurality of switching phases to control the inductor current in the switchable inductor, the duration of the switching phases being determined from at least one of a reference inductor current value and a reference output voltage value. The predictive controller includes a supervisory controller coupled to the DC-DC controller and configured to set a reference inductor current value dependent on an expected change in load current and/or voltage of a load configured to be connected to the load terminal. The expected change in load current and/or voltage is determined from a predetermined load profile.
