Abstract
A method for determining if an inductor coupled to a switching network has been electrically shorted may include applying a voltage across the inductor for a predetermined period of time, controlling an impedance in an electrical path of a voltage source generating the voltage and the inductor, sensing an inductor current through the inductor, 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.
