The paper discusses the universal current sensor fault detection and compensation mechanism, which can be applied in three-phase power electronics symmetrical system. The mechanism is based on the assumption that a symmetrical system can be described using different components in the stationary reference frame. The solution named in the papers as a Cri-based detector was tested in electrical drives with Induction Motors (IM) and Permanent Magnet Synchronous Motors (PMSM). This paper is also proved that the same algorithm can work stable in active rectifier systems. Such an application of this detector has not been previously reported in the literature. The paper describes the detection of various types of faults in different phases. The Fault Tolerant Voltage Oriented Control (FTVOC) of an active rectifier is compared with previously described solutions for IM and PMSM. By analyzing in various types of systems, the work proves the universality of the detector based on Cri markers.
