IGBT(Insulated Gate Bipolar Transistor)，绝缘栅双极型晶体管，是由BJT(双极型三极管)和MOS(绝缘栅型场效应管)组成的复合全控型电压驱动式功率半导体器件, 兼有MOSFET的高输入阻抗和GTR的低导通压降两方面的优点。GTR饱和压降低，载流密度大，但驱动电流较大;MOSFET驱动功率很小，开关速度快，但导通压降大，载流密度小。IGBT综合了以上两种器件的优点，驱动功率小而饱和压降低。

数字控制的交流调速系统所选用的微处理器、功率器件及产生PWM波的方法是影响交流调速系统性能好坏的直接因素。在介绍了正弦脉宽调制(SPWM)技术的基础上，设计了一种以8098单片机作为控制器，以智能功率模块IPM为开关器件的变频调速系统。通过软件编程，产生正弦脉冲宽度调制波形来控制绝缘栅双极晶体管的导通和关断，从而达到控制异步电动机转速的目的。实验结果表明，该系统可调频率调电压，稳定度高，调速范围宽，具有较强的实用价值 Abstract: AC variable speed with digital control systems used microprocessors， power devices and generate PWM wave is the direct factors of affecting the performance AC speed regulation system. On the basis of introducing the sinusoidal pulse width modulation (SPWM) technology，this paper designed variable speed system which used 8098 as a controller， intelligent power module IPM as switching device. Through software programming， resulting in sinusoidal pulse width modulation waveform to control the insulated gate bipolar Transistor turn on and off， so as to achieve the purpose of speed control of induction motors. Experimental results show that the system can adjust frequency modulation voltage， high stability， wide speed range， has a strong practical value.
