Abstract
The two-input buck (TIBuck) post-regulator has been proposed to improve the dynamic characteristics of conventional power factor correctors (PFCs). This post-regulator exhibits very high efficiency due to the fact that only a part of the total power undergoes a power conversion process and, therefore, the overall efficiency of the complete converter is very close to that of the first stage. In this paper, the implementation of a PFC based on a conventional flyback and a TIBuck is analyzed
