摘　　要：三相功率因数校正(PFC)有许多优点,但其实现很复杂。而单相PFC技术已经发展的很成熟,因此可以用单相PFC来实现三相PFC。本文分析了利用单相控制方法实现三相功率因数校正的优点。介绍了几种利用实现的方法,并分别给出了相应的结构框图和电路拓扑。对各种结构进行了简单的比较,对它们的各自的特点进行了相应地介绍。最后,综合考虑其优点,此方法有一定的实用价值。The advantages of three-phase power factor correction （PFC） are obvious but it s always complicated to be realized. However, the single-phase PFC has been well developed and it is relatively easy. So, the three-phase PFC can be realized by the single-phase control method. Advantages of the realization from single-phase control to three-phase power factor correction are analyzed in this paper. Several different types of methods about using single-phase control to realize the three-phase power factor correction are introduced and corresponding circuit topologies are given. Various structures are compared, and their respective characteristics are introduced. Finally considering its merits, this method has a certain market value.
