This paper discusses the compare of a series of power factor correct circuit design and simulation method.. And at this foundation through the Dispersed Domine Analyse the paper makes a great emphasis on the application of computer aided design and simulation, then designs a series of APFC design and simulation software. This paper takes out a set of designation and simulation on base of actual circuit. The reliable result, output voltage and inductance current which are got from this software are the same as the actual value. The model of circuit recurs the running course and reflects the working mechanism of the actual circuit. |
