Modeling of the three-phase inverter of the asynchronous motor and analysis of working characteristics

Бесплатный доступ

In the article methods of frequency and voltage regulation are considered on the example of a three-phase autonomous voltage inverter (SIN) with sinusoidal pulse width modulation (PWM) at a carrier frequency. Based on the obtained results, the difference in the values of the moment and voltage, obtained by calculation and modeling, was calculated. A variant of the PWM control of a three-phase asynchronous motor is considered, characterized by the minimum harmonic components, electric and magnetic losses, the torque spread with respect to the mean value. An adequate model of a three-phase inverter of an induction motor is proposed.
