 摘  要

    由于交流变频调速技术的发展，特别是变频器的问世，在许多宽幅度调速的场合，给交流电机逐步取代直流电机提供了可能性。目前，随着交流调速系统的不断完善，己在相当大的领域代替了直流调速系统，如造纸、轻工、纺织印染、冶金、机床等许多行业均普遍开始采用交流调速系统。本课题采用IR2130（国际整流器公司最新推出的高压集成驱动器， 可作为交直流调速、UPS电源、电子镇流器以及永磁无刷电机调速电路中主功率元件的驱动电路）直接驱动六个绝缘栅晶体管(IGBT)。再由单片机根据正弦脉宽调制(SPWM) 控制技术（工业控制领域中特别是在三相电机的控制中应用最为广泛的一种变频电源控制的技术）输入六路脉来冲控制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.

Keywords：Frequency Control； IR2130； IGBT； sinusoidal pulse width modulation (SPWM)；the inverter
