Abstract: Relevance. This paper analyzes vibration and noise problems in induction motor drives caused by higher harmonics of pulse converters. Existing compensation methods are limited by the size and weight of the power filter, the variable switching frequency of the converter transistors, or the high computational demands on the drive controller. Purpose of the study. Developing a novel pulse converter topology and an original synthesis method for an adaptive voltage regulator aimed at purposefully improving the spectral composition of output currents to minimize vibroacoustic effects in inductor motor drives. Methods. The work employs principles and methods of linear control theory and electromechanical system modeling. Novelty. A switching converter topology with output voltage closed-loop control is proposed, featuring an original synthesis method for an adaptive voltage regulator of a voltage source inverter. The developed control ensures regulation of controlled variables and targeted improvement of the output current spectral composition. Results. It is demonstrated that this approach improves the spectral composition of the converter's output currents, thereby minimizing the vibroacoustic effects of the drive. Practical significance. The developed control system can be implemented in industrial, transportation, and household electric drive systems where requirements for acoustic comfort, reliability, and equipment compactness are critical.
