Abstract
A system for detecting faults in a rectifier includes an AC current generator and a rectifier. A controller is configured to determine an AC input current supplied to rectifier, generate a simulated rectified DC input current based upon the AC input current, and determine a DC output current from the rectifier. The controller is further configured to compare the simulated rectified DC input current to the DC output current and generate an alert command if a difference between the simulated rectified DC input current and the DC output current exceeds a predetermined difference threshold.
