数字化电源功率因数校正器的设计

Designing of PFC of Digital Switching Power Supply

本文以单相功率因数校正器(PFC)为对象讨论了如何设计数字电源,重要的是讨论了单相PFC的小信号模型,在这个基础上阐明了电源双环控制的组成,详细讨论了设计控制器的方法,完善了从小信号建模等理论直到完成整个数字化电源控制的过程,并对具体的工程技术问题给出了具体的分析手段和可操作的解决方法。

Take single- phase power factor correction for example, this paper discusses how to design digital power supply. More importantly, this paper discusses the small signal model of single - phase power factor correction. On this basis, this paper illustrates the composition of double - link control of digital power supply and discusses the methods of designing controller in detail. In addition, this paper consummates the theory of small signal modeling till the whole process of power supply of digital control is finished, and then puts forward concrete analysis means and operative solution in view of specific technology problems
