Abstract

Frequency-controlled electric drives constructed according to the scheme “frequency converter–ac electric motor” are widely used in modern technology and electric drive systems of various vehicles. At the moment, many methods of modulating the voltage at the output of the frequency converter have been developed in order to bring its shape closer to the sinusoidal one with the lowest losses. Since, depending on the task at hand, different characteristics of voltage modulation are prioritized, it is necessary to know the advantages and disadvantages of the main algorithms for generating voltage at the output of the frequency converter. A feature of high-power electric drive systems is the impossibility of using high switching frequencies of the power switches of the frequency converter, which makes it necessary to know the laws of the formation of the voltage spectrum when using a particular method. The article considers the basic algorithms for generating voltage at the output of a frequency converter without feedback: scalar and spatial-vector pulse-width modulation and computational algorithms for voltage formation, as well as a comparative analysis of the spectra and the nonsinusoidality coefficient at comparable switching frequencies of power switches, performed both analytically, which gives an idea of the principles of forming the voltage spectrum, and by modeling processes in MATLAB/Simulink.
