摘要：The diagnosis of the electric systems is an actual item for the specialists in domain. The direction is interesting due to the multitude of the measuring points and large number of possible faults to be analyzed. The algorithms used for determining the normal/fault operation use new concepts and automatic systems as the expert systems. The proposed diagnosis system based on the analytic model investigates the output waveforms of a rectifier for two types of possible faults of the switches: interrupted and short circuit. For identifying the elements in fault, the waveforms corresponding to different faults are stored in an information database and compared with the ones corresponding to normal operation.
