摘要(Abstract)：

用于风力发电的AC-DC整流器接口电路,需要对感应发电机或永磁同步发电机提供无功功率。采用空间矢量分析方法,对一种传统的用于单位功率因数校正的串联双Boost型三相脉宽调制(pulse width modulation,PWM)整流器进行了研究,并分析了该电路的有功和无功处理能力,表明该电路可以在超前或滞后30°功率因数角的范围内工作,适用于风力发电系统中的三相PWM整流器接口电路。同时该电路的共模电压幅值比常规的6开关PWM整流器减少33%,且仅用2个高频开关,因而具有一定的工程实用价值。

关键词(KeyWords)： 风力发电;脉宽调制整流器;接口电路;共模电压
