Abstract (en)
[origin: WO2012010557A1] Method of detecting a fault in an alternator (50) providing a three-phase electric current to a load (100), the method comprising the steps of: - determining a duty ratio of each of the phases at the output of the alternator, - determining a phase shift between the phases at the output of the alternator, - determining a presence of a fault as a function of the phase shift and of a comparison of the duty ratios. Power supply device for the implementation of this method.
