Method of detecting a fault in a permanent-magnet alternator and power supply device comprising a detector module

A method of detecting a failure of an alternator supplying three-phase electricity to a load, the method comprising the steps of determining a duty ratio for each of the phases at the output of the alternator, determining phase differences between the phases at the output of the alternator; and dete...

More Information
Summary:A method of detecting a failure of an alternator supplying three-phase electricity to a load, the method comprising the steps of determining a duty ratio for each of the phases at the output of the alternator, determining phase differences between the phases at the output of the alternator; and determining the presence of a failure as a function of the phase differences and as a function of a comparison of the duty ratios. A power supply device is also provided for implementing the method.
