Abstract
The technology development of AC frequency conversion speed regulator, especially the appearance of transducer, makes it possible for AC motor substitute DC motor gradually on many wide range speed governing occasions. At present, the AC speed regulator has replaced DC speed regulator system with its perfection. Many industries have already adopt AC speed regulator system, such as, papermaking, light industry, textile printing and dying, metallurgy, machine tool. This subject adopts the technology that the IR2130 ( which is high voltage integrated circuit driver newly studied and developed by international rectifier company. And IR2130 could be used as the DC speed regulator, UPS power, electronic ballast as well as driving circuit of power components in permanent magnet and brushless motor speed regulation circuit.) drives six isolated gate IGB transistors directly, and with the control technology of singlechip according to SPWM( which is one of the most common control technologies for variable-frequency power sources in industrial control, especially in three phrase machine control), to control IR2130 with the six input three-phase.
