Fault Detection and Diagnosis of 3-Phase Inverter System

However, only a study of an open loop volt/Hz speed control strategy of an induction motor have been done as reported in the literature above. This paper presents experimental results on condition monitoring and fault detection of transistor base drive open-circuit faults of a 3-phase voltage source inverter (VSI), fuzzy controlled induction motor.

What is Active Front End in variable frequency drive?

Active Front End (AFE) variable frequency drive has some harmonic filtering at the input to the VFD that is "programmable" on the fly. Basically, a microprocessor "brain" in the VFD monitors the harmonics being generated by the power electronics and "actively" supplies a waveform through the filters to dampen the upstream harmonic content.

Feb 01, 1996· A commonly used technique for the detection of faults which may occur in three-phase induction motors is to carry out a spectral analysis of the supply current to the motor under investigation. The presence of certain frequency components within the spectral analysis has been shown to be indicative of a fault condition (Hargis et al., 1982).
