THE ALGORITHMS OF HIGH-VOLTAGE FREQUENCY CONVERTERS CONTROL AND ASSESSMENT OF THEIR INFLUENCE ON PARAMETERS OF FILTER-COMPENSATING DEVICES

In the article the actuality of the field of study has been presented ? the realization of requirements of minimum possible distortion of current and voltage curves and the design of effective structure of high-voltage electric drive. The suggestions concerning the structure of block IGBT- frequency converter have been grounded and given. The algorithm of formation of the trapezoidal integral curve of output voltage and algorithm of the cyclic by-turn switching of blocks of converter has been studied providing the decline of the dynamic losses in transistors and the increase of efficiency factor of the whole electrotechnical complex. The method of calculation of the L-type filter has been suggested.
