К вопросу исследования характеристик форм кривых выходного напряжения структуры инвертор напряжения – асинхронный двигатель

Abstract

The analysis of the work leads to the conclusion that the formation of variants trapezoidal output voltage signal quality better by reducing the number of switching points during synchronous switching power transistors in all phases of the inverter. Increase the frequency of the carrier signal does not lead to the exclusion of a number of harmonic components of the output voltage, and to their movement toward higher frequencies. Therefore, an important moment in the formation of a variety of pulse width modulation switching frequency inverter power switches.
