| 摘 要： | 目前在电力电子技术研究领域,具有隔离和功率因数校正功能的单级AC-DC变换器,均是依赖于全桥整流的新型变换器。当前的单相AC-DC变换器是基于传统的脉宽调制(PWM)变换方法实现的,它至少包括3个不同的功率信号处理级:全桥整流器、BOOST PFC变换器和串联隔离式全桥DC-DC变换器,共用到14个开关器件和3个磁性元件,这些都对变换器的效率、尺寸和成本限制产生影响。本文所介绍的混合变换方法,实现了一种新型单级AC-DC变换器拓扑结构,是一种只包括3个开关器件和1个磁性元件的非桥型PFC变换器。这种变换器具有98%左右的效率、0.999的功率因数和总共仅1.7%的谐波畸变。三相整流器包含了3个这样的单相整流器,它利用了特斯拉三相转换系统的优点,可以进行三相系统的输入功率到直流输出功率的瞬态转换,具有高频光隔离,0.999的功率因数,低谐波畸变(1.7%),较小的尺寸和成本等特点,而且效率达到了98%。。
