Заглавие: Теоретичен анализ и моделиране на хармоничния състав на напрежението в асинхронни честотни електрозадвижвания
Ключови думи: Electrical drives, harmonic spectra, sinusoidal PWM, frequency converters

Абстракт: Electrical drives consume more than 65% of produced electricity. Over 90% of them are three-phase induction motors with an average efficacy between 70% - 90% that are used mostly in industrial plants. The increase of the number of power electronic converters (often frequency converters with intermediate DC link) enhances the need to further examine the problem of their impact on the motors. This paper presents a theoretical evaluation of the harmonic spectra of frequency converters voltage. Basic concepts and quantitative assessment of non-sinusoidal periodic signals are classified. An approach for determining the harmonic spectra of the voltage by sinusoidal PWM is presented. Simulation models for analysis of non-sinusoidal periodic signals are developed. The possibilities of using these signals directly or with sinusoidal filters for supply of induction motors in operation mode and for testing are analyzed.

Abstract: Electrical drives consume more than 65% of produced electricity.

This paper presents a theoretical evaluation of the harmonic spectra of frequency converters voltage. Basic concepts and quantitative assessment of non-sinusoidal periodic signals are classified. An approach for determining the harmonic spectra of the voltage by sinusoidal PWM is presented. Simulation models for analysis of non-sinusoidal periodic signals are developed. The possibilities of using these signals directly or with sinusoidal filters for supply of induction motors in operation mode and for testing are analyzed.
