It is assumed in this paper that the aim of a power electronic converter diagnostics is to find out the actual converter?s state and to automatically formulate a diagnosis to correct it. The result of the diagnostics? operation was either confirmation of the converter?s correctness or detection and isolation of the faults. To formulate the diagnosis the paper uses fast orthogonal transforms. A direct frequency converter is considered as an example, in which the diagnostics was based on using an algorithm of a fast Haar transform. The control of the converter and its diagnostics were set up employing parallel processing, which enabled the real-time requirements to be met.
