摘 要

电压型三相逆变器就是供给逆变器的交流电源是三相电电源， SPWM正弦脉宽调制法这项技术的特点是原理简单，通用性强，具有开关频率固定，控制和调节性能好，使输出电压只含有固定频率的高次谐波分量，并能够消除谐波，且设计简单等一系列的优点，SPWM正弦脉宽调制法是一种比较好的波形改善的方法。SPWM正弦脉宽调制法的出现为中型和小型逆变器的快速发展起到了一个重要的推动作用。伴随着电力电子技术的高速发展，电压型三相SPWM逆变器已被广泛应用在各个领域之中，并且SPWM技术已经成为目前应用最为广泛的逆变用PWM技术。

通过电压型三相SPWM逆变器建模和仿真研究这项课题，能够加强自己对电压型三相SPWM逆变器控制原理和建模进行深入理解，并提高自己在三相电压逆变方面的计算机仿真能力，为今后自己从事交流电机控制与电源逆变相关工作打下良好的基础。

电压型三相SPWM逆变器建模和仿真研究

Abstract

The AC power supply voltage three-phase inverter is supplied to the inverter is three-phase electric power supply, the technology of SPWM sine pulse width modulation method is simple in principle, strong versatility, with fixed switching frequency, control and regulation performance, so that the output voltage harmonic component contains only the fixed frequency, and can eliminate the harmonic, and has the advantages of simple design a series of, SPWM sine pulse width modulation method is a good waveform improvement. SPWM sine pulse width modulation method for the rapid development of medium and small inverter plays an important role in promoting. Along with the rapid development of power electronic technology, three-phase voltage-source SPWM inverter has been widely used in various fields, and the SPWM technology has become the most widely used PWM technology of inverter.

Through research on Modeling and Simulation of three-phase voltage-source SPWM inverter this subject, it can make me have a strength to voltage three-phase SPWM inverter control principle and modeling a more depth understanding, and it can improve myself in the three-phase voltage inverter aspects of computer simulation ability, which can make me have a good foundation of engaged in AC motor control and power inverter related work.
