The paper discusses current issues on the inverters peculiarities in the frequency converter. Theoretical studies have been carried out to determine the influence of the induction motor mode on the current modulation in the DC link. The authors suggest a calculation technique to determine the form of transient current characteristics when exposed to a single pulse of the inverter. Model studies of the system, calculation and construction of current characteristics proved the correspondence of theoretical and practical results. The research results determined the relationship between the current modulation in the DC link and the induction motor mode of operation.
