IMPULSE MODEL OF A FREQUENCY MATRIX CONVERTER
Abstract:

The variant of matrix converter is considered, which can be used at the last testing any others frequency converters in processes their development and production. The current changing in active-inductive load circuits is analyzed at the inverter control of converter based on state-space vector pulse-width modulation. There is performed the synthesis of impulse model for matrix frequency converter. The parameters of the model is found on the basis of the current equivalency in the model and in the converter load circuit at the beginning and end of the converters discrete-time interval. The model adequacy is carried out. There is determined that at the voltage constant value on the inverter input the error of the model is within 0.1 %. The effect of invertors input voltage fluctuations is considered. The significant increase of the model maximum error is obtained. There is proposed to compensate the inverters input voltage changing based on the measurement of the voltage mean value during the interval of pulse-width modulation and taking into account this result at the converter control.
