This paper proposes a new fault diagnosis methodology for of high power factor rectifiers. This method Is based on the combined with input line currents three dimensional space and the use of the on Principal Component Analysis (PCA). With the proposed method it is possible to detect and identify the power switch in which the fault has occurred. Such detection requires only the measurement the rectifier input currents. Simulation and experimental results are presented, considering for both healthy and faulty cases, to demonstrate the correctness of the proposed method.
