Fault detection investigation in a full bridge thyristor base AC-DC converter

In this paper firstly, best method identification for data acquisition selection by aim of fault analysis is presented and in continue, a new pattern for a full bridge thyristor base AC-DC converter under failure in view of series hybrid electric vehicle (SHEV) application is identified and presented by the help of experimental test result. Open phase signatures are utilized to introduce a particular frequency pattern, and side-band components changes at proposed frequencies are employed as a proper index for fault recognition.
