Abstract
A new method to improve dynamic response of power factor preregulators (PFP) is developed in this paper. The method is based on the use of a very high efficiency post-regulator with two inputs instead of only one. This two-input post-regulator exhibits very high efficiency due to the fact that only a part of the total power undergoes a power conversion process. They need two-output PFPs at their inputs, which can easily be obtained in PFPs with transformers or with two PFPs working in parallel.Keywords
