A DC component in voltage-source inverters with pulse-width modulation and ways of compensating for it
Tóm tắt
The causes of the appearance of dc components in the output voltage of voltage-source inverters controlled by the method of pulse-width modulation (PWM) are shown. Two different variants to compensate for the causes of appearance of the dc component for a sinusoidal PWM and one variant for a vector PWM are suggested.
