摘要
A new method to improve the dynamic response of power-factor correctors (PFC's) is described in this paper. The method is based on the use of a new very highly efficient postregulator, called a series-switching postregulator, This new postregulator exhibits very high efficiency due to the fact that only a part of the total power undergoes a power conversion process. The proposed postregulator can be used with any PFC topology (either with or without a transformer), with no modifications in the topology, and can be easily protected against short circuits.
