A method or system consistent with this invention for detecting if a thyristor failed open in an alternating current input phase of a load comprises measuring an instantaneous power delivered to the load during a cycle of the input; determining a peak power delivered to the load during the cycle of the input; calculating an average power delivered to the load during the cycle of the input; and determining if the thyristor failed open by comparing the magnitudes of the peak power and the average power.

L'invention concerne un procédé ou système servant à détecter unedéfaillance d'état conducteur d'un thyristor, dans une phase d'entrée de courant alterné d'une charge, et consistant à mesurer unepuissance instantanée fournie à la charge lors d'un cycle d'entrée,à déterminer une puissance de crête fournie à la charge lorsducycle d'entrée, à calculer une puissance moyenne fournie à la charge durant ledit cycle, et à déterminer si le thyristor a présentéune défaillance d'état conducteur, en comparant les amplitudes dela puissance de crête et de la puissance moyenne.
