عنوان المقالة:استخدام الموجة الجيبية والنبضات المعدلة لقيادة المحرك التاثيرى لخفض تموجات العزم وتقليل التوافقيات Sinusoidal PWM to Drive the Induction Motor with Reducing the Torque Ripple and THD
—Three phase voltage source inverter are widely used
to drive the AC motors as the induction motor. There are many
techniques to make the inverter reliable to treatment the AC
motor. From among these techniques, the sinusoidal pulse width
modulation. The paper used this technique due to have some
advantages as, reduce the total harmonic distortion and torque
ripples. Also in this Paper the open and closed loop scalar controls
with the sinusoidal pulse width modulation are compared to show
the advantages of the closed loop control. The torque ripples and
total harmonic distortions is calculated through many modulation
index. The PI current controlled is added to the closed loop drive
system to minimize the torque ripple and total harmonic distortion
this is to show the effect of adding these PIs on the performance
overall.
