摘  要

    由于交流變頻調速技術的發展，特別是變頻器的問世，在許多寬幅度調速的場合，給交流電機逐步取代直流電機提供了可能性。目前，隨著交流調速系統的不斷完善，己在相當大的領域代替了直流調速系統，如造紙、輕工、紡織印染、冶金、機床等許多行業均普遍開始采用交流調速系統。本課題采用IR2130（國際整流器公司最新推出的高壓集成驅動器， 可作為交直流調速、UPS電源、電子鎮流器以及永磁無刷電機調速電路中主功率元件的驅動電路）直接驅動六個絕緣柵晶體管(IGBT)。再由單片機根據正弦脈寬調制(SPWM) 控制技術（工業控制領域中特別是在三相電機的控制中應用最為廣泛的一種變頻電源控制的技術）輸入六路脈來沖控制IR2130。

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.
