A method for supplying power to an inductive load including an H-bridge switching structure coupled to a power supply and including a first, a second, a third and a fourth switch and current measurement means designed to measure a current through each switch, the power supply method including: a) supplying power to the inductive load, b) reducing an accumulated current in the inductive load. Upon detection of an anomaly: c) identifying the switch that caused a circuit break, d) identifying whether the anomaly was detected during step a) or step b). If an anomaly is detected in step a): e) performing step b) for a third duration, f) identifying the origin of the anomaly, g) if an anomaly is detected in step b): h) identifying the origin of the anomaly.
