Target-oriented classification of frequency converters (FC) for electric drives is given including the use of the converters with a link of increased frequency. The description of methods of pulse density modulation (PDM) is made; their classification is given. Expression to calculate the FC output voltage harmonics are derived provided that PDM is used. An influence of modulator output voltage frequency on FC output voltage harmonics is investigated.
