Abstract:
The paper presents the general approach to the problem of the principles of operation and waveforms of electric variables of electronic power converters by means of space vectors. The method of describing the operation of the electronic valves, e.g. thyristors, enables the mathematical description of the converter corresponding to the real operation of the system. The hodographs of the vector functions of electric values may be used to the diagnostics and current control of the converters operation (monitoring) [2]. In the diagnostic circuit output level may be used fuzzy or neural fault detectors which determine a kind of fault and make a signal of it appearance.
