1. A method for determining if an inductor coupled to a switching network has been electrically shorted, comprising:
applying a voltage across the inductor for a predetermined period of time;
controlling an impedance of a switch in an electrical path of a voltage source generating the voltage and the inductor while the switch is activated in order to limit an inductor current through the inductor during the predetermined period of time;
sensing the inductor current;
comparing the inductor current with a predetermined current threshold; and
determining whether the inductor has been electrically shorted based on the inductor current, the predetermined current threshold, and the predetermined period of time.
