Description
FIELD: electricity. SUBSTANCE: control method for frequency matrix converter in the form of a matrix with nine twodirectional semiconductor keys, installed in nodes, wherein the keys have a two-sided current conductivity, is that using a pulse-width modulator control impulses of the two-directional keys are shaped, which are modulated in width by comparing alternate reference signal and nine modulating harmonic signals, which change in time at angular frequency, which is equal to the desired angular frequency of the output voltage, and designed in such a way that at any specified output frequency of the frequency matrix converter under load there is no constant component of voltage and subharmonics, multiple of the frequency of the supply line voltage. They implement the possibility of organizing the mode of linear modulation and overmodulation of the output voltage of the converter. EFFECT: increase in the transmission gain of the frequency matrix converter.
