| 摘 要： | 为了提高功率因数,抑制谐波污染,在交流调速领域越来越多地采用了PWM整流技术.PWM整流器定频开关控制策略主要有SPWM和SVPWM两种调制方式.在Matlab环境中建立了两种调制方式下的仿真模型,并进行了对比分析.仿真结果表明,SVPWM控制方案系统的鲁棒性增强,动态性能有很大提高,可使系统得到更高的功率因数.针对SPWM直流电压利用率低和谐波分最严重的缺点,采用了基于SVPWM的电流内模解耦控制方案,将基于VME总线的嵌入式系统应用到PWM整流器中,控制器硬件采用VMIC系列高性能控制器.实验证实了该方案的有效性,系统响应速度快,直流母线电压稳定,实现了单位功率因数运行.

| Abstract: | To increase the power factor and restrain the harmonic pollution,PWM rectifier is widely used in drive system. The fixed switch frequency control strategy of the PWM rectifier has two main methods,SPWM and SVPWM.Both of the strategy's modes are established with the tool of Matlab,the results show that both the robust and the dynamic performance of the system are upgraded under the SVPWM control strategy,and the power factor is also increased than SPWM. Aiming at the weaknesses that the SPWM control method a... |
